I've seen two by fours being used as ramps get shot out behind a car becoming dangerous missiles. And I've seen expensive valances and exhaust pipes damaged when loading a prized vehicle on a ramp with too high an angle. Do you own a really, really low vehicle? Here's how to load and unload your baby without harming the front or rear of the car. The 6.78° incline allows use for the lowest of vehicles. Made from high-density expanded polystyrene they are tough yet amazingly lightweight. Coated with a hybrid polyurea coating that is highly textured providing a high-grip surface so your tires won't slide and they are easy to clean. Measuring 45" long and 14" wide they have a 1,500-pound weight capacity per ramp, yet weigh only 6 pounds each. They make a perfect addition to our Two Piece Vehicle Ramps. Be smart and be safe!
