The Challenger 670-90928 installation and operation manual 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 installation and operation manual 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: 670-90928
• Brand: Challenger
• Type: Genuine OEM installation and operation manual

Fasteners and small hardware fit by more than just thread size. Grade matters — a hardware-store bolt in a load-bearing spot doesn't have the strength of the rated fastener it replaced — and length, head type, and locking feature all have to match. Anchor bolts especially are engineered for the load and the concrete. Grabbing whatever's in the bin for a structural fastener is exactly the kind of shortcut that fails under shock load.

Replacing your installation and operation manual

Replacing structural hardware means matching the original's grade, size, and length — not just what fits the hole — and torquing it to spec, especially on anchors and load-bearing fasteners. Confirm nothing is left loose or under-grade. Because the wrong fastener fails under shock load, the complete walkthrough is worth following start to finish. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it.

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 it's time to replace it

The miscellaneous check: airlines free of cracks and leaks with a clean lock release; decals present and legible; hardware tight, correct grade, and rust-free; air pressure steady; the correct manual on hand; no missing pins, clips, or guards. None of these carries the car by itself, but together they're the difference between a lift that's merely running and one that's actually right.

Parts commonly replaced at the same time

Ask about the companions. Even a minor part is a chance to handle the other items your lift is due for, and we can pull the parts breakdown for your model to see what usually pairs with it. One order, one delivery, fewer trips up the ladder.

Safety notes

Do not treat the small stuff as optional. Missing or unreadable decals fail an inspection, and an under-rated accessory in the wrong place is a real hazard. Match the part to your model, install per the manual, and keep the lift the way it was certified to run.

Before you order

Have your model and serial handy and tell us what you are solving — even small parts have the right and wrong version for a given lift. We will make sure you get the correct one so you are not waiting on a reorder.

Ordering the right revision

Before this goes in the cart, grab two things off your lift: the model number and the serial number, both on the manufacturer's plate. The serial matters more than most people expect — lift makers revise components between production runs without renaming the lift, and the run your serial falls in determines which revision of this part is correct.

If you are working from a failed part rather than a plate, measure what you have and photograph how it mounts. Send that to us along with the lift brand, and we will check it against the same parts breakdowns our own techs use in the field before you commit to the order.
