Wehrli Custom Fab ARP up-pipe bolt kit for 2017–2025 Duramax L5P replaces the smaller, failure-prone 8mm OEM fasteners with 12 high-strength ARP bolts, matched washers and a packet of assembly lube to improve serviceability and reduce the risk of seizing or breakage in the manifold or turbo pedestal. This kit is intended as a direct upgrade for both stock and modified trucks, offering a cost-effective peace-of-mind replacement where factory fasteners have shown reliability issues.
