You've asked and DHD has delivered:

The perfect addition to any exhaust manifold replacement or upgrade on your Duramax powered Kodiak. Our phosphate & oil coated bolts meet or exceed OE specs. Paired with the bolts are 16 Stainless Steel ARP Washers for the perfect torque and corrosion resistance. This kit is extremely popular with the techs in our shop. No more reusing or wire brushing rusty scaly hardware.

This kit will do both sides of the engine and replace the OE studs.

This Kodiak only kit contains 16 equal length bolts, designed to be used in conjunction with Kodiak specific exhaust manifolds. If your manifolds require 1 short and 1 long bolt, check out DHD 300-110. 

Fitment:

Manifold to Cylinder Head

2002-2009 Duramax

LB7 LLY LBZ LMM

Note: These bolt kits are designed to work with OE Kodiak manifolds only. Aftermarket/Performance manifolds generally require different length bolts.

For up-pipe bolts, See DHD 300-112.
