Goodyear Gatorback timing belt kits are designed to deliver precise, non-slip timing over the life of your engine. Designed to meet or exceed O.E. recommendations, these kits include timing belts, tensioners, idlers, and complete installation instructions where applicable. These kits use Goodyear's exclusive Wingprene synthetic rubber and feature precision-molded teeth, a tough synthetic facing, and high-strength synthetic cords. All materials are selected to ensure consistent performance and long-term durability in the hot, oily environments of today's crowded engine compartments.
