The XDP Starter Bolt Kit (Black-Phosphate) XD533 will replace the corroded starter bolts on your 2001-2022 GM 6.6L Duramax. The starter is situated in the lowest part of the engine compartment, where it is subjected to the elements like rain, mud, and snow. Your starter bolts experience the same abuse as well as noise, vibration, and harshness (NVH) while holding your 20-pound starter in place.

These XDP starter bolts have a durable black phosphate finish to withstand harsh road conditions. This tough coating offers higher adhesion, improved anti-galling properties, and corrosion resistance. These bolts come in a package of 2 and will meet or exceed the factory standards.
Features:

• Direct-Fit Replacement
