The Challenger 3W-02-14 arm restraint gear 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 arm restraint gear 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: 3W-02-14
• Brand: Challenger
• Type: Genuine OEM arm restraint gear
• Fits: SA10

Lock parts wear slowly but steadily every time the lift cycles. Each engagement bangs the pawl against a tooth; over thousands of cycles the contact faces peen over and round off. Dirt and dried grease build up in the pivot until the pawl gets lazy. A commercial lift that racks up cycles all day will round its lock teeth years before a low-use lift does — but neglect and rust can age either one fast.

The locks are the lift's mechanical backup — the part that actually holds the vehicle up once it's raised. A spring-loaded pawl drops into a toothed ladder at each column, and the lift rests on steel, not on hydraulic pressure. Hydraulics raise the lift; the locks are what let you work under it. Every click you hear on the way up is a pawl catching a tooth, ready to catch the whole load if pressure is ever lost.

Replacing your arm restraint gear

Replacing a lock ladder means getting the old one off its mounts, fitting the new one so the teeth line up with the pawl's travel, and securing it with no play. Then cycle the lift and watch the pawl catch a full tooth at every height. Because this is the lift's last line of defense, the full procedure is worth following start to finish. Full step-by-step: how to replace lift arm restraint gears.

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 the locking system needs attention

Test engagement under the lift's own weight: raise it, then lower onto the locks and watch each pawl seat fully into a tooth. Any pawl resting on the tip or shoulder of a tooth instead of down in the root isn't fully engaged, even though it looks set. Shallow engagement usually traces to a worn tooth, a worn pawl nose, or the lift sitting unlevel.

Parts commonly replaced at the same time

Lock hardware works as a set, so when one part is worn the others usually are too — latches, pawls, springs, and the release cable all age together. Doing the full lock rebuild on both columns at once keeps engagement even and saves a second teardown. We will assemble the complete lock kit for your model.

Safety notes

The locking system is the last line of defense on a lift, so a worn latch or sticky pawl is a safety defect, not a nuisance. Both columns must engage and release together; if one clicks late or drags, the lift comes out of service until it is corrected. Never defeat or wire back a lock to keep a lift running.

Before you order

Have your model and serial ready, and note whether you need parts for one column or both — even lock wear is best corrected as a set. If the release cable is stretched or frayed, order it alongside the latch and pawl. Not sure which version your lift uses? Send a photo of the old parts.

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.
