Detailed Product Description

The Gates PowerGrip Premium OE Timing Belt T251 is manufactured using a modified curvilinear (iii) tooth profile, which improves the belt's engagement with the camshaft and crankshaft sprockets. This design reduces noise and wear, contributing to longer service life. The belt's 32 mm top width and 8 mm pitch ensure it fits precisely within the valve train components of compatible vehicles. Constructed with fiberglass cords, the belt maintains high tensile strength and flexibility, while the HSN (Hydrogenated Nitrile) belt material offers resistance to heat, oil, and abrasion. The inclusion of timing marks simplifies installation and alignment, helping maintain accurate engine timing critical for performance and emissions control.
