2001-2016 Duramax Up Pipe / LB7 Down Pipe Bolt Kit

Bolts that will not seize or snap

The aging factory bolts that hold the up pipes to the exhaust manifolds and turbo pedestal on 2001-2016 Duramax engines, and the LB7 down pipe to the turbo outlet, often seize or break, which Wehrli says it has seen many times in its development work.

This kit replaces them with 6 high-strength 12-point ARP bolts, matched washers and ARP assembly lube, enough for one up pipe. Buy two kits to do both up pipes. It is a simple upgrade for stock or modified trucks that makes later service easier.
