The Challenger A1077TC arm restraint gear is the direct replacement for the Challenger lift it came off of. This is the genuine Challenger part — same fit and same working specification as the one already on your lift. Ordering the Challenger arm restraint gear from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: A1077TC
- Brand: Challenger
- Type: Genuine OEM arm restraint gear
- Fits: CL10, CL10A, CL10DPC, CL10V3
Lock ladders and pawls are matched geometry — the tooth pitch, the nose angle, and the mounting have to suit the specific lift. A ladder that almost fits will let the pawl sit shallow on the tooth, which is worse than obvious because it looks engaged and isn't. Match restraint parts to the actual lift model and column, not a close-enough substitute, because the whole point of the part is that it holds under full load.
Locks don't work in isolation — they depend on the release mechanism and the leveling of the lift. The lock-release cable or air cylinder pulls all pawls at once so the lift comes down even; if the lift isn't level, one pawl loads before the others and wears first. So when locks click unevenly, the cause can be the ladders, the pawls, the release, or stretched cables. Diagnose the set, not just the noisy corner.

Replacing your arm restraint gear
Swapping restraint gear or a safety latch is about restoring the positive stop that catches the load if something upstream lets go. Install the part, then trip it by hand and under the lift's own weight to confirm it deploys fully and clears on release. This is safety-critical hardware, so the step-by-step procedure is worth following start to finish. Full step-by-step: how to replace lift arm restraint gears.
Find the right part for your lift
Not certain this is the exact part your lift needs? Start with your lift's model and serial off the data plate, then open our Challenger parts lookup to see the visual parts breakdown for your model — the exploded drawing with every part numbered and priced. If your plate is missing or unreadable, our guide to finding your model number walks through where to find it, or send us a photo and we will identify the lift for you.
Signs the locking system needs attention
Check that the ladder is tight on its mounts. A ladder that has loosened, shifted, or cracked at a bolt hole moves under load, which changes where the pawl lands and can let it slip past a tooth. Grab it and try to move it; there should be no play. Any give at the mounting means the ladder needs re-securing or replacing before the locks can be trusted.
Parts commonly replaced at the same time
The parts around a lock failure share its wear: a rounded latch usually rides with a tired spring and a stretched release cable. Do them together on both columns so the lift locks in step. Tell us your model and serial and we will pull the complete lock hardware set.
Safety notes
Locks are the redundancy that makes a lift safe to stand under, so treat any lock problem as urgent. If teeth are rounded, a pawl sticks, or the release cable is frayed, fix it before the next vehicle. Confirm synchronized engagement and clean release on both sides, and never bypass a balky lock to buy time.
Before you order
Order lock parts by model and serial, not by guess — the hardware changed across production runs. Since both sides should lock in step, plan to replace in pairs, and bundle the release cable if it is worn. We will match the correct latch, pawl, and spring set for your lift.
Check your lift's serial before ordering
The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.
Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
