The Challenger B40116 sheave 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 sheave from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

Lift cables don't have a fixed lifespan; they have an hours-and-conditions lifespan. A busy shop that cycles a two-post twenty times a day wears cable and sheaves far faster than a home garage that lifts once a week. Grit, road salt dragged in on frames, and a rough sheave groove all speed it up. Most sets that see daily commercial use start showing broken strands somewhere in the five-to-ten year window.

The cables, sheaves, and lock-release parts on a lift make up the tension path — the mechanical chain that ties both carriages together and keeps them rising at the same rate off a single cylinder. Steel cable runs over grooved sheaves, and small release cables trip the safety pawls so the lift can come down. Every one of these parts lives under constant load whenever a vehicle is in the air, which is exactly why they wear.

Replacing your sheave

Getting a tension part in and adjusted is well within a capable shop's reach, but it's exacting: correct routing, correct order on the retention hardware, and careful equalization so no single lock takes the load first. Rush the adjustment and the lift arrives at the top crooked. For that reason the whole procedure is worth following step by step. Full step-by-step: how to replace car lift sheaves.

Find the right part for your lift

Want to be sure before you buy? Pull the model and serial off your lift's plate and open our Challenger parts lookup to open the exploded parts breakdown for your model — find your part on the drawing and you know it fits. New to finding your model number? our guide to finding your model number covers it, or send a photo of the plate and we will read it for you.

Signs a cable or sheave is worn out

For the lock-release cable, pull the handle and watch every pawl. They should all pop out of their ladders together. A pawl that lags, or a release cable that feels frayed or has lost tension, means the cable or its spring is failing. Check it for the same broken strands and corrosion as any other cable — it's thinner, so it goes faster.

Parts commonly replaced at the same time

When a cable or sheave goes, the rest of the set is usually close behind — they share the same hours and the same wear. Most shops replace all the cables together and refresh the sheaves in the same visit, because the labor to open the columns is the same whether you change one part or the set. Ask us to build the full cable-and-sheave kit for your lift and you order once.

Safety notes

Treat every cable and sheave on a lift as load-bearing until proven otherwise — because it is. Replace tension parts in matched sets so they wear evenly, never reuse a cable that has been kinked or run slack, and set the carriage on its mechanical locks before you put a wrench on anything under tension. A cable that lets go does not fail politely.

Before you order

Have the lift's model, serial, and the old part in front of you when you order. Tension parts vary by production year and by standard-versus-extended height, and the fastest way to get the right one is to match length and fittings against what came off. Call and we will confirm before it ships.

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.
