Wehrli 17-24 Chevrolet/GMC 6.6L L5P Duramax Up Pipe Bolt Kit

When you're working on the exhaust system of your 2017-2025 Chevrolet or GMC 6.6L L5P Duramax truck, this up pipe bolt kit from Wehrli is what you'll want to have on hand. This kit includes 12 specially selected high-strength ARP fasteners and matched washers, along with a pack of ARP assembly lube. These are designed to replace the smaller, 8mm factory bolts that connect the up pipes to the exhaust manifolds and turbocharger pedestal.

Wehrli has seen the factory fasteners seize or break even on new trucks in rust-free areas. This kit offers a simple and cost-effective upgrade to give you peace of mind and make servicing your truck easier, whether it's stock or modified. Using these stronger ARP bolts helps prevent common failures and ensures a more secure connection for your up pipes.
