The grand lifestyle that goes hand in hand with 5th wheel towing is made perfect in the details. You can talk all you want about whose RV hogs the most road or whose 5th wheel hitch can handle the most tonnage, but when you get down to it, the best hitch and trailer setup in the world can never reach its full potential without the right accessories to back it up. CURT 5th wheel rail sound dampeners are made to fit between a 5th wheel hitch and its mounting rails. These neoprene pads are made to eliminate the clanking and rattling noises common while driving with a 5th wheel hitch. Each pack includes four sound-dampening pads.
