RitFit M2 3D vs P9 is not a contest between two bar styles, because both machines carry a 3D Smith bar. The difference is cable loading and price: the M2 3D is listed at $2,199.99 with plate-loaded cables, while the P9 is listed at $1,999.99 with a built-in 198 lb steel weight stack.
This comparison sticks to published specifications: footprint, ceiling clearance, cable ratios, frame ratings and price. Every number comes from the RitFit product pages, so you can match a machine to your garage bay and your training plan.
Quick Answer: The RitFit M2 3D vs P9 decision comes down to how you load the cables. The M2 3D lists at $2,199.99 with a plate-loaded cable system, a 2,000 lb published maximum and 22.8 sq ft of floor space, while the P9 lists at $1,999.99 with a 198 lb integrated steel stack, switchable 1:1 and 2:1 ratios and a 19.8 sq ft footprint.
Key Takeaways
- Same bar, different loading: the M2 3D and the P9 both use a 3D Smith bar, so the real split is cable loading and price rather than movement style.
- M2 3D price: RitFit lists the M2 3D at $2,199.99, and its cable system is plate loaded with no built-in stack.
- P9 price: RitFit lists the P9 at $1,999.99 with a 198 lb integrated steel stack at 99 lb per side.
- Footprint: the M2 series occupies 22.8 sq ft and stands 86.14 inches tall, while the P9 occupies 19.8 sq ft and stands 85.2 inches tall.
- Frame figures: RitFit publishes a 2,000 lb maximum for the M2 series and a 1,600 lb frame for the P9, with the P9 component ratings listed separately.
- Later stack: the WSM2 stack set adds a 286 lb stack to the M2 and M2 3D and is listed at $1,159.99.
RitFit M2 3D vs P9: Specs Side by Side
The RitFit M2 3D and the RitFit P9 share a 3D Smith bar, so their published specifications separate them on price, cable loading, footprint and frame ratings. RitFit lists the M2 series at 78.7 inches long, 68.75 inches wide and 86.14 inches high, and the P9 at 63.4 x 78.6 x 85.2 inches as published. The M2 3D is listed at $2,199.99 and the P9 at $1,999.99.

Figures as published on the RitFit M2 series and RitFit P9 product pages, read in September 2026. Frame figures are the published frame ratings, not a working weight for any single component.
Keep the RitFit M2 3D page and the RitFit P9 power cage page open if you want to check a row against the source, because the two tables label the same measurements in different ways.

M2 3D vs P9: What the Price Gap Actually Buys
The P9 is listed $200 below the M2 3D and ships with a weight stack, so the extra money on the M2 3D buys frame capacity and floor space. RitFit lists the M2 3D at $2,199.99 and the P9 at $1,999.99, and the M2 configuration table tells the same story: the built-in dual 286 lb stack appears on the M2 3D vs M2 Pro vs M2 Pro 3D comparison, not on the M2 3D.
- The $2,199.99 M2 3D: a 2,000 lb published maximum, 22.8 sq ft of floor space, 2.36 x 2.36 x 0.08 inch 13-gauge uprights and 10 adjustable 3D Smith positions, with cables you load from your own plates.
- The $1,999.99 P9: a 1,600 lb frame, 19.8 sq ft of floor space, 2 x 2 inch 14-gauge uprights and a 198 lb steel stack at 99 lb per side.
- The trade you are actually making: loading plates on a carriage against pulling a pin on a stack, which is a training-room preference rather than a quality gap.
The M2 3D runs a 2:1 cable ratio, and the P9 can switch between 1:1 and 2:1, so how pulley ratios work decides how heavy each machine feels at the handle.
Read the price gap as a description of two loading designs, not as a ranking. The cheaper machine carries a stack, and the pricier one carries more steel and more floor space.
"Set it up by myself, not ideal, but definitely doable! Just used it for the first time and it is incredible. One stop shop piece of equipment"
Taylor C. Verified Buyer, RitFit M2 Multi-Functional Modular Home Gym Smith Machine Tailored to All Fitness Levels
M2 3D vs P9: Cable Loading and Resistance Ratios
The M2 3D runs a plate-loaded cable system at a 2:1 pulley ratio, while the P9 pairs a dual-slider cable system with a 198 lb steel stack. The P9 ratios switch between 1:1 and 2:1 across 15 cable height positions per side, and the M2 3D carries a 33 lb Smith bar on a 2,000 lb published maximum frame. Both machines sit in RitFit's Smith machines lineup, and that shared platform is why the cable system is the deciding part.
Two lifters can train on opposite sides of the P9 at the same time, because each side carries its own 99 lb stack. The M2 3D loads plates on the carriage instead, so two users share the plates that are already loaded, and the machine never runs out of resistance as long as you own the plates.
For a solo lifter, the practical question is how fast you can change weight between a warm-up set and a working set. A stack changes in one pin move, while plates on the M2 3D carriage take the same time as loading a barbell.
"The 3d motion is smooth and feels like one is being spoiled. Cables glide over the pulleys and appreciate how they keep releasing new accessories to expand it's versatility."

M2 3D vs P9: Footprint, Ceiling Clearance and Garage Fit
Both the M2 3D and the P9 fit under a standard 8-foot ceiling, because RitFit lists the M2 series at 86.14 inches tall and the P9 at 85.2 inches. The M2 series covers 22.8 sq ft of floor and the P9 covers 19.8 sq ft, so the larger machine is also the deeper one at 78.7 inches front to back.
- Height: the M2 series stands 86.14 inches and the P9 stands 85.2 inches, so each clears a standard 8-foot ceiling with several inches left over.
- Floor space: the M2 series needs 22.8 sq ft at 78.7 x 68.75 inches, and the P9 needs 19.8 sq ft at 63.4 x 78.6 inches.
- Layout: measure the wall run behind the rack and the depth of your bay, then leave working clearance above the pull-up bar and around the frame for plates and a spotter.
- Small single bay: a 19.8 sq ft footprint on a 63.4 inch width leaves more walking room around the P9, while the 68.75 inch width of the M2 series suits a bay wide enough for a bench beside the rack.
A tighter floor plan also changes which attachments you can leave on the frame, so weigh power rack and Smith machine combos against the space you actually have.

M2 3D vs P9: The 3D Smith Bar Path
Both machines use a 3D Smith machine bar, so the bar floats forward and back through a set of positions instead of tracking one fixed vertical line. RitFit lists 10 adjustable 3D Smith positions on the M2 series and six locking positions in fixed and free modes on the P9, with about 20.6 inches of horizontal bar travel on the P9. More index points give finer control over where the bar floats, which matters most on presses and rows.
A 2023 systematic review and meta-analysis of 13 studies found no significant between-modality difference for dynamic or isometric strength, so the guided 3D bar is not a handicap by itself [1]. One 2026 trial found similar 1-RM gains across range of motion conditions but different bar kinematics, which is the part a 3D carriage changes [2].
The what a 3D Smith machine is explainer covers how the carriage geometry works, and 3D Smith machine exercises shows what the shared bar unlocks in a garage setup.
"Training in the floating range means your primary movers and the stabilizing muscles around the lift both have a job to do. For hypertrophy work at moderate to sub-maximal loads, that middle ground produces a training feel that is genuinely different from a standard Smith machine."

M2 3D vs P9: Frame Capacity and Component Ratings
RitFit publishes a 2,000 lb maximum for the M2 series and a 1,600 lb frame for the P9, and the P9 page also lists its component ratings one by one. The M2 series uses 2.36 x 2.36 x 0.08 inch 13-gauge uprights, while the P9 uses 2 x 2 inch 14-gauge steel. Those figures describe frames and parts, so none of them is a working weight to load on the bar.
- P9 pull-up bar and safety arms: 660 lb each as published.
- P9 Smith module: 530 lb static and 265 lb dynamic.
- P9 single-side pulley: 550 lb static and 330 lb dynamic.
- Hardware check: seat your J-hooks and safety arms before a heavy set, because the published figures are frame and part ratings rather than a working weight.
- M2 3D: a 2,000 lb published maximum on the frame, with a 33 lb Smith bar as the only published bar figure.
The RitFit P9 guide walks through where each rating applies on the cage, and the same logic applies to the M2 3D. Set your safety arms at the height where you actually fail, because even a guided bar path needs a catch height below your sticking point.
For durability, the gauge numbers are the comparable part: 13-gauge steel on the M2 series is thicker than 14-gauge steel on the P9, and thicker uprights typically show up as less frame movement when you re-rack heavy squats.
"Best Piece of equipment that I've ever owned. Very smooth!"
Jacob S. Verified Buyer, RitFit M2 Multi-Functional Modular Home Gym Smith Machine Tailored to All Fitness Levels
Which RitFit All-in-One Should You Buy?
Choose the machine that matches your loading preference and your floor plan, because both units train the same compound patterns through a 3D Smith bar and a cable system. A 10-week trial in novice males reported comparable gains in muscle size, strength and functional ability whether the subjects trained with machines, free weights or a mix of the two [3].
Choose the RitFit M2 3D if You Want the Bigger Frame and More Bar Positions
This is the better fit when you squat and press heavy, want 10 floating bar positions and can spare 22.8 sq ft of floor. You load your own plates, and the stack becomes a separate purchase if you ever want one.
"Assembly was pretty straightforward, knocked it out the same day I recieved that last boxes. A few pieces had some dings but not super noticeable. Everything arrived in 3-4 days. Overall I am extremely satisfied, this thing is a beast and does everything I want."
Bradley P. Verified Buyer, RitFit M2 Multi-Functional Modular Home Gym Smith Machine Tailored to All Fitness Levels
Pick the RitFit P9 if You Want a Built-In Stack for Less
This is the better fit when you train alone, want to change weight with one pin and want two lifters on the cables at the same time. The 19.8 sq ft footprint and the $1,999.99 price make it the easier fit for a single garage bay.
If your budget is the binding constraint, the RitFit P3 power cage is listed at $689.99 with a 17.53 sq ft footprint and a 1,200 lb frame, and it does not include a 3D Smith bar or a built-in stack. Read RitFit P3 vs P9 and RitFit M1 vs M2 before you step down a tier, because the differences sit in bar travel, stack hardware and footprint rather than in build quality.
Is the M2 3D or the P9 Worth the Price?
The P9 delivers more loading hardware per dollar, and the M2 3D delivers more frame and floor space per dollar, so each price is defensible for the buyer it fits. RitFit lists the M2 3D at $2,199.99 and the P9 at $1,999.99, and the WSM2 stack set that closes the M2 3D stack gap is listed at $1,159.99.
- Buy the M2 3D at $2,199.99 if: you already own plates, you want the 2,000 lb published maximum and the 22.8 sq ft platform, and you may add a stack later.
- Buy the P9 at $1,999.99 if: you want the 198 lb stack, the switchable 1:1 and 2:1 ratios and the smaller 19.8 sq ft footprint on day one.
- Buy a smaller RitFit cage if: a $689.99 P3 covers your lifts, or your ceiling and bay cannot take either frame.
Compare power rack packages only after you decide how you want to change weight, because that decision outlasts a $200 price gap.
"Definitely worth the price for what you get. Assembly was easy. I did it by myself. Took around 2 1/2 hours. Will definitely be ordering more equipment from RitFit!"

M2 3D vs P9: What Upgrades Cost Later
The M2 3D has a published stack upgrade path and the P9 does not need one, because the P9 already ships with its 198 lb stack. The WSM2 weight stack set is listed at $1,159.99, fits the M2 and the M2 3D and adds 286 lbs through 13 pieces at 11 lbs on each of two sides.
- M2 3D plus WSM2: $2,199.99 for the machine and $1,159.99 for the stack set, which RitFit cites as adding up to 452 lb per side.
- P9: the 198 lb integrated stack is already inside the frame, so later spending goes to attachments rather than to weight.
- Weight plates: the M2 3D loads from your own plates, so a plate set belongs in its total cost from the start.
The stack question is really a timing question: buy weight up front with the P9, or start with plates on the M2 3D and add the WSM2 when your training demands it.

FAQs About the RitFit M2 3D and P9
What is the difference between the RitFit M2 3D and the P9?
The M2 3D is a Smith machine platform with a 2,000 lb frame, 22.8 square feet of floor space, and a plate-loaded cable system. The P9 is a power cage with a 1,600 lb frame, 19.8 square feet, and a built-in 198 lb steel weight stack. The P9 costs less.
Does the M2 3D come with a weight stack?
No. The M2 3D ships with a plate-loaded cable system rather than a built-in stack. RitFit lists built-in dual 286 lb stacks only on the M2 Pro and M2 Pro 3D. You can add the WSM2 weight stack set, which is listed at $1,159.99 and fits the M2 and M2 3D.
Which machine fits a garage with an 8 foot ceiling?
Both fit. The M2 series stands 86.14 inches tall and the P9 stands 85.2 inches, so each clears a standard 8 foot ceiling with several inches left over. Leave extra room above the pull-up bar, and check length and width against your wall space before ordering.
How many 3D Smith positions does each machine have?
RitFit lists 10 adjustable 3D Smith positions on the M2 series and six locking positions in fixed and free modes on the P9. The P9 also publishes about 20.6 inches of horizontal bar travel. More index points give finer control over where the bar floats on the M2 3D.
Can two people train on the same machine at once?
The P9 is built for it. Its dual-slider cable system lets two users train on opposite sides at the same time, and each side carries its own 99 lb stack. The M2 3D uses a plate-loaded cable system, so two lifters share the plates loaded on the carriage.
Is a 3D Smith machine as effective as free weights?
Peer-reviewed comparisons suggest the two produce similar overall strength and hypertrophy outcomes. A 2023 meta-analysis of 13 studies found no difference between modalities for dynamic strength, and a 10-week randomized trial in novice males reported comparable gains in strength and function.
Conclusion
RitFit M2 3D vs P9 comes down to how you want to load the cables and how much floor you can spare. The M2 3D gives you a 2,000 lb maximum, 22.8 sq ft and 10 floating bar positions at $2,199.99, while the P9 gives you a 198 lb integrated stack, switchable ratios and a 19.8 sq ft footprint at $1,999.99.
Measure your ceiling and wall run first, then check stack and plate costs against the machine you are leaning toward. Open the RitFit discount guide before you order, and pick the loading system you will still enjoy.
