Is your trailer door too steep to get your car to the track or autocross? Are you tired of hauling around heavy, unsafe boards to use as a makeshift ramp extension? Race Ramps has the solution for you: simply place your trailer door on the notch of our specially-designed Trailer Ramps and decrease your angle of approach to as little as 4.3 degrees.
These hassle-free, lightweight ramps are ideal for low-ground-clearance cars with extra-wide tires. Numerous size options are available in our one- and two-piece designs, with and without flap cut-outs. Use our ramp calculator above to determine which Trailer Ramps will work best for your car and trailer, and let us know if you have any questions. We are happy to make a custom set if our standard options don't work—just give us a call!
Trailer Ramps are 100% solid, made with an exclusive patented process that coats high-density expanded foam with a traction surface for a lightweight ramp solution that is strong yet durable. The ramps will not slide, scratch, or otherwise damage any floor type and can hold up to 1,500 lbs. per ramp for a total vehicle weight capacity of 6,000 lbs.
Both enclosed and open trailers work with our Trailer Ramps. If your stock trailer ramps have an additional fold down ramp/flap, you can fold it up, remove it, or purchase a ramp that has a flap cut-out built into the ramp (check the appropriate box below).
Measure from the ground to the top of your current trailer door/ramp at the hinge point.

Measure from the ground to the top of your current trailer door/ramp at the hinge point.

Measure the thickness of trailer door/ramp.

To determine the best angle of approach for your vehicle, we have devised the “yardstick test” below. If you do not have a yardstick, carefully measure out 36" with a tape measure or other straight, rigid object. You may need two sets of hands to get an accurate measurement here.
YARDSTICK TEST
- Place a yardstick/tape measure at the base of your front wheel.
- Raise up the yardstick or tape measure until it hits the underside of your car (the spoiler).
- Measure vertically from the ground to the end of the yardstick or 36" point on the tape measure. Record that height here (in inches).

Service Ramp Type | Angle of Approach | Maximum Tire Width |
---|---|---|

"Hit the road" takes on a whole new meaning when it's in reference to driving your high-performance sports car onto standard trailer ramps that are just too steep. Get the extra ground clearance you need to load your low profile car and keep from bottoming out with these specialized trailer ramps from Race Ramps™. Notched edges on each ramp allow the trailer door to securely rest on the ramps, suspending the door off the ground for additional clearance.
