The Challenger B31037 replacement hardware 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 replacement hardware from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

When a lift gets its annual inspection, the hardware is where a trained eye lingers. Inspectors look for exactly the things this bucket of parts is bought to fix: pins with visible slop, sheaves wobbling on worn bushings, copper-colored bushing material creeping out the side of a sheave, lock springs too tired to snap a pawl home, and chains with tight links or visible stretch. Every one of those is a write-up, and every write-up is a bay out of service until the fix is documented. The economics are lopsided: the hardware costs little, the failed inspection costs the downtime, and the difference between the two outcomes is usually a walk-around you can do yourself in ten minutes.
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.
Do the inspector’s hardware pass: grab each sheave and try to wobble it by hand with the load off — real wobble is a worn pin or bushing. Look for bushing material showing at the sides of sheaves. Cycle the locks and watch that every pawl snaps back smartly; a lazy pawl is a spring. Look for bright rub marks and metal dust anywhere parts move against each other.
A lock pawl with a weak or broken return spring can fail to engage while looking perfectly normal from the floor. Anything in the lock train — springs, pins, pawls — gets replaced on condition, immediately, not monitored. The locks are the part of the lift that catches everything else.
