This is a complete set of up-pipe gaskets for your OEM or OEM replacement up-pipes on your 2001-2016 GM 6.6L Duramax diesel. These up-pipe gaskets are compatible with the LB7, LLY, LBZ, LMM and LML Duramax engines. Save money by getting OEM quality gaskets without the OEM price! Whether you need one replacement up-pipe bolt because it broke or you need a full set, Rudy's has you covered! We recommend installing a full set of bolts so you never have to worry about breaking a stock bolt again. These bolts secure the up-pipe to the exhaust manifold and turbo assembly, feature a black finish and have a 12 point head. These bolts are Grade 12.9 providing a substantial extra margin of safety over Grade 8 hardware. The stock bolts have tendency to break when reused, so skip the hassle and replace them when the up pipes are already out!

Features:

• 1-Year Warranty
• Full set of 12 for both up pipes
• Grade 12.9 for additional strength
