Challenger RJ3.5 Rolling Jack For 4 Post Lift
You've got a CL4P7 four-post lift in the bay and a wheel-off job rolling in. Without a four post lift rolling jack you're stuck pulling the vehicle off and repositioning to a two-post. The Challenger RJ3.5 fixes that. Roll it into position, pump the handle, and the wheels come off the runways while the vehicle stays put.
This is a 3,500 lb. capacity hand-pump rolling bridge jack for 4-post lifts, built specifically for the Challenger CL4P7. Hand operation keeps it simple, no shop air required. If you've been working around the limits of a four-post, this is the accessory that turns it into a true wheels-free service platform.
Why This 4 Post Lift Rolling Bridge Jack Earns Its Spot
| Hand Pump Operation | No shop air required. Pump and go, anywhere on the runway. |
| Built-In Rollers | Slide the jack along the rails with one hand instead of muscling it into position. |
| Mechanical Lock | Loads the weight onto a positive lock so you're not relying on hydraulic pressure mid-job. |
| Powder-Coated Finish | Resists rust and wipes down clean after fluid jobs and brake work. |
| CL4P7 Direct Fit | Mounts to the runway rails with four hex bolts. No modifications, no adapters. |
| Adjustable Lift Pad Arms | Extend out to reach the vehicle's pickup points without repositioning the whole jack. |

Applications For A 4 Post Car Lift With Rolling Jack
Turn your CL4P7 service rack into a wheels-free workstation for brake jobs, tire rotations, and suspension work.
Lift one axle at a time without moving the vehicle. Ideal for tire mounting, balancing prep, and TPMS service.
Speeds up multi-point inspections where you need wheels off but the vehicle staged on a four-post.
Full undercarriage access without losing the long, stable runway of a four-post setup.
Installation & Setup
Place the jack assembly across the lift rack rails, center it between the runways, then tighten four hex bolts (two per side) to lock the side members in place. Run the jack through a couple of full cycles unloaded to bleed the system before you put it to work. Annual maintenance is simple: check pump oil if the jack stops reaching full height, and inspect for leaks during your daily walkaround.

Frequently Asked Questions
Will the RJ3.5 fit my four-post lift?
The RJ3.5 is engineered specifically for the Challenger CL4P7 four-post lift. It mounts to the runway rails with four hex bolts and centers between the side members. If you're running a different model or aren't sure of your lift's exact spec, call us with your full model and serial number before ordering and we'll confirm fitment.
Does it need shop air or an electrical hookup?
No. The RJ3.5 is a manual hand-pump rolling jack. There's no air line, no power cord, and no compressor requirement. You pump it up by hand and lower it by turning the valve handle counterclockwise.
What's the actual lifting capacity?
3,500 lbs per jack, with hydraulic pressure at capacity of 3,200 PSI. For most cars and light trucks that's enough to lift either the front or rear axle when the vehicle is properly centered on the rack and load is evenly distributed across both lift pads. Always lift at the manufacturer's recommended pickup points.
How tall is the jack when fully lowered?
Drive-over height is 3 inches. Low enough to let vehicles roll on and off the four-post rack without catching the jack as it sits on the runways.
Can I use one jack alone, or do I need a pair?
One RJ3.5 lifts one axle at a time. Many shops run a single jack and reposition it for front or rear work. If you want to lift both axles simultaneously for full wheels-free service, you'll need two units. Each is rated at 3,500 lbs independently.
What hydraulic oil should I use, and how often do I check it?
AW32 10wt non-foaming, anti-rust hydraulic oil. Check the level annually, or sooner if the jack stops reaching full rise height. With the jack fully lowered, remove the pump from the base, hold it vertical, pull the breather plug, and top off to the filler hole.
What if I need replacement parts down the road?
Every component on the RJ3.5 has a Challenger part number, from the hand pump to the wheels to the snap rings. We can source any part on the breakdown directly from Challenger. Call (855) 498-2147 with the part number or describe what you need and we'll get it ordered.
