The Challenger B12621 carriage component 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 carriage component 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: B12621
• Brand: Challenger
• Type: Genuine OEM carriage component
• Fits: CL12, CL12A

The arm pad is the rubber or poly contact point between the steel arm and the vehicle's lift point. Its whole job is to grip and to protect the pinch weld or frame from the hard steel underneath. Every pad is a wear item by design — it compresses, hardens, cracks, and eventually tears or crushes flat, at which point it stops gripping and starts letting the car slide.

Replacing your carriage component

Replacing column hardware — anchors, arm-pin retainers, slide blocks, fasteners — is about restoring the tight, no-play fit the structure was built with. Use the correct grade and torque, and confirm the column sits flat and solid to the floor afterward. The complete procedure lays out what to check and in what order. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it.

Find the right part for your lift

If you are not sure this part matches your setup, the fastest check is the visual breakdown: open our Challenger parts lookup, pick your model, and match your part against the drawing where every item is numbered. Can't read the model plate? our guide to finding your model number shows exactly where it lives on each lift type, and we are a phone call away if you would rather have us confirm it.

Signs this part is worn out

Watch the lift hold a vehicle. With a car on the arms, look for any pad that squirms, any adapter that rocks, any arm that settles or rotates. Movement under load that shouldn't be there points straight to a worn pad, a bent adapter, a wallowed pin hole, or a loose retainer. The car sitting rock-solid is the pass; anything shifting is a part to find and replace.

Parts commonly replaced at the same time

Smart to replace the group: contact points wear together, so pads, adapters, and their pins are best done in one pass. It keeps the lift level and the vehicle secure. We will build the matched structural kit for your model so you are not chasing one worn pad at a time.

Safety notes

Structural wear sneaks up: a pad flattens, a hole elongates, a ramp lip curls, and one day the vehicle is not sitting where it should. Treat these as safety parts, not cosmetics. Replace them before they let a load shift, and confirm every mounting point is tight and true before the lift carries weight.

Before you order

Before ordering, confirm your lift's model and serial and check how many of the part you need — pads and adapters usually go in sets of four, and replacing one worn one still leaves three worn. Match the old part's shape and mounting against what you order, and call if the fit is not obvious.

Not sure this fits? Here's how to check

Pull the number off your lift's model plate first — model and serial both. Manufacturers run mid-cycle revisions that keep the model name but change hardware, so two lifts with the same name on the column can take different parts. The serial is what removes the guesswork.

Second check: compare the old part against this listing before you order. Length, mounting pattern, and thread sizes tell most of the story. If anything doesn't line up, or if the old part is too worn or broken to measure, call us with photos — we work on these lifts every week and can usually confirm fit from a picture and the lift's serial faster than you can dig through a parts diagram.
