Engine Parts
Want to get miles and miles out of a belt? Choose an Alliance™ Parts serpentine or fan belt for your truck's engine. Fitting all makes and models of heavy-duty trucks, our serpentine belts are made from high-strength ethylene propylene diene monomer (EPDM), which lasts significantly longer than traditional neoprene belts. In addition, Alliance™ serpentine belts resist rib cracking, and offer improved load, wear and heat resistance. While you’re changing out your serpentine belt, you might want to replace your old tensioners with Alliance™ Parts tensioners. Built with patented technologies, these tensioners are designed to stand the test of time, ensuring smooth operation with less wear and tear. Find the belt you need in our parts listings.
