The Challenger ALIF-440-100 is the direct-replacement safety latch for the Challenger lift it came off of — the genuine part, same fit and same working specification as the one already on your lift. Ordering the Challenger safety latch 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: ALIF-440-100
• Brand: Challenger
• Type: Genuine OEM safety latch
• Fits: 44040, 44050, 44060

A safety latch is the positive stop that keeps a raised component — an arm, a carriage, a locking device — from dropping if something upstream lets go. It's designed to do nothing at all until the moment it's needed, which is exactly why it gets ignored. A latch that's rusted, bent, or missing its spring is a latch that won't be there in the one instant it matters.

There is no part on a lift where "I'll get to it later" is more misplaced than the locks. This is the component that holds a car over a technician's head. A rounded tooth or a sticky pawl gives no second warning — it holds until the day it doesn't. Restraint gear and safety latches are cheap and the labor is modest; skipping them to save an afternoon trades a small job for a catastrophic one.

Replacing your safety latch

Lock work usually pairs with checking the release and the leveling, since uneven clicks can come from the ladder, the pawl, the release, or stretched cables. Replace the worn parts, then adjust so every lock lands together and releases together. Chasing that timing down correctly is the whole job, and the full walkthrough covers how. Full step-by-step: how to replace a lift lock ladder.

Find the right part for your lift

If you are not sure this part matches your setup, the fastest check is the visual breakdown: open our Challenger parts lookup, pick your model, and match your part against the drawing where every item is numbered. Can't read the model plate? our guide to finding your model number shows exactly where it lives on each lift type, and we are a phone call away if you would rather have us confirm it.

Signs the locking system needs attention

For safety latches and restraint gear, verify the part actually deploys. Trip it by hand and confirm it swings or drops fully into its stop, then springs clear on release. Look for bends, cracks at welds, seized pivots, and missing springs or pins. A latch that's stiff, partially seized, or bent won't reach its stop in the instant it's needed — which is the only instant it exists for.

Parts commonly replaced at the same time

Since the lift has to come down to its locks safely on both sides, service the lock hardware as a unit — latch, pawl, spring, cable, both columns. Half a repair leaves uneven engagement. We will build the full lock kit for your lift so it catches and releases together the way it should.

Safety notes

Every lift is designed to rest on its locks, not its hydraulics — which is why worn lock hardware is so dangerous. Replace latches, pawls, and release cables before they hesitate, verify both columns lock and release in step, and take any lift with an unreliable lock out of service on the spot.

Before you order

Before ordering lock parts, confirm your lift's model and serial — latch, pawl, and release-cable designs changed over the years. Replacing the lock hardware as a set on both columns keeps engagement even, so order for both sides unless you know only one is worn. Call if you need to match an older design.

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.
