With the Silent Hitch Pin, enjoy the sound of silence. Let's Go Aero's patented Silent Hitch Pin eliminates shock loads from the hitch connection by removing the free-play between the hitch and the tow device. The result is motionless towing and a quiet ride. Let's Go Aero brands include a broad range of hitch based cargo carriers, bike racks, lightweight trailers, and car port shelters that take the hassle out of travel so you can focus on the fun.
