Product Description

The ARP 230-4203 Head Stud Kit is a precision-engineered upgrade tailored for the 2.8 L Duramax LWN diesel engine found in 2016-2022 Chevrolet Colorado and GMC Canyon models. Crafted from ARP's proprietary ARP2000® alloy and heat-treated to 220,000 psi tensile strength, these studs offer exceptional durability and clamping force - critical in high-pressure diesel environments.

Each stud is centerless ground and thread-rolled after heat treatment for optimal fatigue resistance and concentricity. Finished in black oxide for corrosion protection, the kit includes premium chromoly 12-point nuts, hardened parallel-ground washers, and ARP-Ultra Torque lubricant to ensure accurate torque application and long-lasting head gasket integrity.
