The Challenger B2230C lift arm component is the direct replacement for the Challenger lift it came off of. Cross-referenced as ALS-7234-300B, it is the genuine Challenger part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Challenger lift arm 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: ALS-7234-300B
- Brand: Challenger
- Type: Genuine OEM lift arm component
The restraint gear on a 2-post lift is the toothed gear that engages when the lifting arm swings in under load, locking the arm at whatever angle the tech set it to. When teeth wear round, chip, or the pawl gear that engages into the restraint gear loses its point, the arm can swing under load — and a swung arm with a vehicle on it drops the vehicle. Any restraint gear that will not positively catch the arm under light hand pressure needs to come off, whether the teeth look okay or not.

Confirm this is the right part before you order
Lift manufacturers revise parts mid-production without changing the model name, so the same lift bought two years apart can take two different revisions of the same component. Before you order, find the model plate on the lift — on most 2-post lifts it rides on one of the columns at eye level, on 4-post lifts it is usually on a column or the power-unit side runway — and note the full model number and serial. The serial dates the lift to a production run, and that is what decides which revision fits.
If the plate is painted over or missing, take a photo of the part you are replacing next to a tape measure and send it to us. Between the dimensions, the mounting pattern, and what lift it came off of, we can almost always identify the exact part before you spend money on the wrong one.
Also inspect
- Arm pin — if you had a bad restraint gear you may also have a mushroomed or grooved arm pin
- Foot-pad rubber — intact, securely attached
- Return spring on the pawl
- Arm itself — broken welds, cracks, severe rust
A restraint gear that will not engage is a lift that is unsafe to load. Do not put a vehicle on the lift until you confirm both arms lock positively under hand pressure.

About this cl10 rear middle
The cl10 rear middle is a direct-fit replacement engineered to restore original manufacturer performance on the lift model it services. Every piece we ship carries the exact dimensional and material specifications the OEM published for that application. Fitment on this component is critical: it interfaces with adjacent hardware in ways that any deviation from spec can drive premature wear on nearby parts or trigger the lift's mechanical safety systems into an unexpected condition. Shops that source this from us instead of a generic aftermarket substitute consistently report zero fitment issues on first-time installation.
Technical specification & installation notes
Cycle life on this piece depends heavily on operating conditions. In a typical commercial repair shop running 6-10 lifts per day, the cl10 rear middle should deliver five to eight years of service before showing measurable wear against the OEM inspection specification. In a high-volume tire or alignment shop running 20+ lifts per day per bay, expect service every three to five years. It is designed to be a serviceable component; when it does wear it wears within safe operating margins that trigger visible symptoms — drift, uneven wear, minor leakage — well before failure becomes a safety issue.
Shipping & ordering
Shipping runs 3-5 business days on standard ground to the lower 48 states. Expedited overnight and two-day options are available; call 800-674-9302 before ordering to quote expedited freight. We stock the cl10 rear middle in Iowa and ship same-day for orders confirmed before 2 PM Central. Orders that come in later than that or on a Friday afternoon pick up on the next business day. A tracking number gets emailed to the address on the order the moment the package leaves our dock.
Warranty coverage
Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the cl10 rear middle is a component that eventually needs replacement in normal operation, warranty coverage specifically addresses failure due to manufacturing defect, not failure due to normal end-of-life wear. Our team can help distinguish between the two on a phone call if there is any question after installation — call 800-674-9302 and describe the failure pattern; we will tell you honestly whether it looks like a warranty case.
Cross-reference & fitment
Alternate applications for the cl10 rear middle sometimes exist. Where a common part fits multiple lift models across a manufacturer's catalog, cross-reference sheets show the compatible models explicitly. If you are consolidating parts stock and want to know which of your lifts the piece covers, email the request to [email protected] with a list of the lift models in your bay — we return a compatibility grid showing which lifts accept the replacement and which need a different number.
Questions about the cl10 rear middle? Call our parts desk at 800-674-9302 or email [email protected]. We ship nationwide from our Iowa warehouse and answer fitment questions within one business day.
