The Challenger DX77-10-04 drive-up ramp 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 drive-up ramp 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: DX77-10-04
• Brand: Challenger
• Type: Genuine OEM drive-up ramp

The carriage is the steel weldment that rides up and down the column carrying the arms. It takes the full lifting load through its slide blocks and its arm pins, and it's where cracks and wallowed-out holes show up on a hard-worked lift. A carriage with an egg-shaped arm-pin bore lets the arm rock; slide blocks worn to nothing let the carriage ride steel on steel and cock in the column.

Replacing your drive-up ramp

Carriage or arm work is heavier structural repair — pins, retainers, slide blocks, and load-bearing welds all have to go back sound and correctly torqued. Photograph the assembly before you take it apart, and confirm nothing rocks or has play when it's back together. Since this is the steel carrying the vehicle, the full 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

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 this part is worn out

The structural condemn list: pads crushed, torn, or oil-soaked; adapter lips bent or cradles spread; pin holes egg-shaped; arms bent; slide blocks worn to steel-on-steel; cracks at any load-bearing weld; loose anchors or missing retainers. These parts carry the vehicle directly, so any one of them shifting, rocking, or cracking is a reason to swap the part before the next car goes up.

Parts commonly replaced at the same time

The parts near this one share its job and its wear — pads, adapters, swivel pins, retaining hardware. Doing them together restores an even, secure grip on the vehicle and saves reopening the job later. Give us your model and serial and we will match the complete set.

Safety notes

A lift's contact and locating parts do quiet, critical work — holding a vehicle exactly where it belongs. Crushed pads, bent lips, and elongated holes all erode that hold. Replace worn structural parts promptly, torque mounting hardware to spec, and never load a lift onto a contact point you can see is compromised.

Before you order

Order structural parts by model and serial and in the right quantity — a single fresh pad among three flat ones does not help much. Match the part's shape and mount to the original, and add the mounting hardware if it is worn. We will confirm the correct version for your lift.

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.
