The WCFab L5P Up Pipe Bolt Kit is comprised of 12 specially selected high-strength ARP fasteners and matched washers with a pack of assembly lube are designed as an upgrade to the smaller and failure prone 8mm OEM fasteners employed on the 2017-2024 6.6L Duramax engines to connect the up pipes to the exhaust manifolds and turbocharger pedestal. During our performance development work on these engines, we have seen common occurrences of the factory fasteners seizing or breaking in the manifolds or pedestal on brand-new, low-mile vehicles in rust-free environments. This kit is a simple, cost-effective upgrade for peace of mind and ease of serviceability for stock and modified trucks.
