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 and newer 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.

**Torque to 24 FT LBS**

I purchased a set of these with my wc fab up pipes. These are way better than the factory bolts. The pack of lube that comes with it works well and a little bit goes a long way! If you go through the pain of removing the old bolts. Do yourself a favor and go back in with this set of bolts. They should just sell the up pipes with these bolts as a package deal instead of an add on.
