Have you ever been loading your cherished vehicle onto a trailer and heard that gut wrenching scrape when your spoiler or rear pipes ground out? Made you feel sick didn't it? I once watched a guy loading his vintage Ferrari 250LM using 2X4's so the car's nose wouldn't scrape on the ramp. When he pressed the gas pedal to get his Dunlops® to roll up over the edge, the wood shot out from behind his rear tires like a missile and almost took out a lady standing behind the car! "Danger Will Robinson Danger!" Here's the way to load and unload a vehicle safely and correctly. Our Trailer Ramp Extensions use a unique notched designed allowing you to place the trailer's ramp directly on the Trailer Ramp extension. This decreases the angle of approach for safe, damage free loading and unloading. Made from high-density polystyrene, these ramps are incredibly light weight (only 15 pounds each) yet they have a weight capacity of 3,000 pounds per ramp. The coating is a hybrid polyurea that is extremely textured for maximum grip, even in the rain. Each ramp measures 67" long by 14" wide and 5" tall with a 4° incline. Rent them out next time you're at the track and you'll pay for them in a weekend. Be safe and smart! Proudly made for you in the U.S.A.
