The Challenger DX77ERK-00L 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: DX77ERK-00L
• 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

A slide-block replacement gets the carriage riding square in the column again instead of steel-on-steel. Pull the carriage down, swap the worn blocks, and confirm the carriage moves freely without cocking. It's methodical work with a clear sequence, spelled out in full in the step-by-step guide. 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

Handle the companions while you are at it. The hardware that mounts a worn pad or adapter is often worn too, and the other contact points are on the same clock. One order for the full set keeps the lift even and saves a second trip. Tell us your lift and we will kit it.

Safety notes

The safe grip between lift and vehicle lives in the pads, adapters, and arm hardware — and every one of them wears. A crushed pad or a wallowed-out pin bore is a slip waiting to happen. Change them at the first sign of damage, secure all hardware to spec, and never trust a load to a worn contact point.

Before you order

Ordering tip: contact and locating parts are model-specific and usually come as sets, so count what you need and read the plate before you buy. If the pads are crushed, the pins and hardware around them are often due too — ask and we will tell you what commonly goes together on 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.
