ARP 230-4203 Head Stud Kit for GM Duramax 2.8L LWN Diesel Engine

The ARP 230-4203 Head Stud Kit provides a high-strength replacement for factory head bolts in 2015-2022 GM Colorado and Canyon trucks equipped with the 2.8L Duramax LWN diesel engine. Designed to enhance cylinder head stability and prevent head gasket failure, these studs are essential for both stock and modified applications.

Constructed from ARP 2000 Material, these head studs deliver exceptional tensile strength up to 220,000 PSI, far exceeding the capabilities of factory hardware. Each stud is heat-treated and centerless ground prior to thread rolling and finishing machining, ensuring precision fit and maximum clamping force.

Complete Kit Includes:

• 10 precision-manufactured ARP 2000 head studs
• 10 hardened 12-point chrome-moly nuts
• 10 parallel-ground chrome-moly washers for even load distribution
• 1/2 oz. ARP Ultra-Torque assembly lubricant

All components feature a black oxide finish for superior corrosion resistance. The parallel-ground washers ensure accurate torque readings and uniform clamping pressure across the cylinder head surface. Whether you're building a performance engine or replacing worn factory fasteners, ARP head studs provide the reliability professional engine builders demand.
