The Race Ramps Trailer Mates RR-TM-REAR are a set of lightweight and durable ramps designed specifically for use with trailers. These ramps are made from a special foam material that is strong enough to support the weight of most vehicles, yet gentle enough to not damage the surface of your trailer. The ramps feature a non-slip surface for added safety and can support up to 6,000 pounds per pair. They are perfect for loading and unloading vehicles onto trailers, and their compact size makes them easy to store and transport. These ramps are a must-have for any trailer owner looking for a safe and efficient way to load and unload vehicles.
