The Challenger DX77-ERK is the direct-replacement drive-up ramp 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 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-ERK
• Brand: Challenger
• Type: Genuine OEM drive-up ramp

An arm, its pad, and its adapters work as a stack, and the whole stack has to be sound to hold a car safely. A perfect arm with a crushed pad still slips; a good pad on a bent adapter still won't seat square. The carriage ties the arms to the column, and the column hardware ties everything to the structure. A weak link anywhere in that chain is a weak link under the whole vehicle.

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

The surest way to get the right part is to work from your lift's own breakdown. open our Challenger parts lookup, choose your model, and every part is mapped on the drawing with its number and price. If you cannot find the model plate, our guide to finding your model number explains where each lift type hides it, and our phone line is open if you want a hand.

Signs this part is worn out

On the carriage, check the slide blocks. Pull the lift up and look at the block faces; bare metal, deep scoring, or blocks worn thin mean the carriage is riding steel on steel and cocking in the column. Worn blocks change how the carriage sits, which loads the arm pins and the locks unevenly. Replace them before the carriage starts chewing the column.

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.

Check your lift's serial before ordering

The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.

Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
