The Challenger 16443 lift arm 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 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: 16443
- 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.
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.
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 challenger 16443 crossarm tube
The challenger 16443 crossarm tube 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
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the challenger 16443 crossarm tube correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Placing an order online is the fastest path — add to cart, check out, done. If the shop needs a purchase order, net-30 terms, or a formal quote for a fleet-service contract, our accounts team handles those via email at [email protected] or by phone at 800-674-9302. Volume pricing on the challenger 16443 crossarm tube kicks in at 10+ pieces on the same order for common wear items. Ask about the volume rate specifically before you check out — many fleet buyers stock 6-12 pieces at a time and the discount is meaningful over that shelf life.
Warranty coverage
Return policy on the challenger 16443 crossarm tube follows our store-wide standard: all parts sales are final; exchanges only if the piece arrives defective. In the case of a defective delivery, ship the failed piece back to us at your cost, we verify the defect on receipt, and ship a replacement at ours. Wrong-item deliveries where we made the shipping error follow a different path — we reimburse the return shipping cost and cover freight on the correct part. Contact [email protected] with the order number to start either process.
Cross-reference & fitment
Cross-reference on the challenger 16443 crossarm tube is straightforward: match the OEM part number from the lift's parts breakdown against the number on your original invoice. If the numbers match, the component fits. If your lift's parts breakdown lists a superseded or alternate number, we accept the superseded value on the phone as confirmation of fit. When a manufacturer has issued a running change during production, we track the change in our catalog so ordering by the older number automatically pulls the current-spec replacement.
