Secure Fitment of Up-Pipes with the WCFab

The WCFab L5P Up Pipe Bolt Kit is an affordable and straightforward upgrade for the 2017-2025 6.6L Duramax that helps improve performance, reliability and ease of serviceability on your truck! Made of specially selected high strength ARP fasteners and matched washers, these bolts help prevent failure of the smaller and failure prone 8mm OEM fasteners employed on the 2017 and newer 6.6L Duramax engines that connect the up pipes to the exhaust manifolds and turbocharger pedestal. In short, having some of these high quality fasteners will ensure proper up-pipe maintenance and ensures longevity.
