Replace worn out or damaged garage door pulleys and cables with our low-priced replacement parts from Garage Door Supply Company. We have 3-inch cable pulleys rated at 100 pound, Genie pulley support assembly kits and Chamberlain belt drive idler pulleys compatible with Chamberlain Whisper drive parts. Find chain drive pulley support kits and heavy-duty metal replacement cables for 7-foot and 11-foot-high garage doors.
A broken or frayed cable can not only cause your garage door to operate inefficiently, a broken cable combined with a snapped spring could cause the spring to fly across the garage without a cable in place, causing major damage to both the operator and your garage. Pulleys can wear out, too, causing your garage door to become stuck when the cables can't slip through efficiently. Each of our new (never used or refurbished) replacement parts include a list of compatible garage doors in the description. If you don't see yours listed, call or email our trained technical staff to help you find the right part.
