C8 Corvette Trailer Ramps, MaxRamps MRTX-4, 4-Inch Rise

The MRTX-4 is the lowest trailer ramp MaxRamps builds, and that is exactly why C8 owners buy it. It stands just 4 inches tall at a 5 degree angle, so it bridges the small step at the back of a low-deck trailer without putting the front splitter anywhere near the hinge or the dovetail.

Each ramp weighs about 6 pounds, which means you can toss the pair in the frunk, the trailer toolbox or the back seat of the tow rig and forget about them until load-up. The foam core is wrapped in a polyurea skin that shrugs off oil, coolant and brake fluid, and it will not scratch a trailer deck the way steel or aluminum ramps can.

Pick the 4-inch ramp when your trailer already sits low, or when you are bumping a car up onto a lift pad, a wheel chock line or a short shop transition. If your trailer door or beavertail leaves a taller step, look at the 5, 6 or 7-inch MRTX ramps instead.

Common Questions

Will my Z06 rear tires fit?
MaxRamps rates this ramp for tires up to 12 inches wide. A Stingray runs 305 mm rears, which is right at 12 inches. Z06, E-Ray and ZR1 rears are 345 mm, roughly 13.6 inches, so those cars should use the 14-inch-wide-tire MRTX-8 instead.

How do I know 4 inches is enough?
Measure the height of the step you need to cover, then compare it to the angle chart in the photos. If the step is more than 4 inches, move up to a taller MRTX ramp so the tire is fully supported.
