The WCFab ARP Bolt Kit for 2001-2016 Duramax Up Pipes or LB7 Turbo Down Pipes is comprised of 6 specially selected high strength 12 point ARP fasteners and matched washers with a pack of assembly lube and are designed as an upgrade to the aging OEM fasteners used on the 2001-2016 and newer 6.6L Duramax engines to connect the up pipes to the exhaust manifolds and turbocharger pedestal or the down pipe to turbo exhaust outlet on the LB7. During our performance development work on these engines we have seen numerous occurrences of factory fasteners seizing or breaking in the manifolds, pedestal, or turbine housing. This kit is a simple, cost effective upgrade for peace of mind and ease of serviceability for both stock and modified trucks.Torque to 54 FT LBSReplaces the following GM part numbers: 11611132
