BD Diesel 1045982 Exhaust Manifold Bolt and Spacer Kit for 5.9L/6.7L Cummins

BD Diesel's Exhaust Manifold Bolt and Spacer Kit addresses a critical weakness in aftermarket exhaust manifold hardware. Standard aftermarket bolts are significantly shorter than OEM specifications, which causes them to fatigue and stretch through repeated heat cycles. This leads to exhaust leaks, loss of clamping force, and eventual bolt failure even after re-torquing.

Engineered for Extreme Heat and Durability:

• Grade 10.9 flange head bolts deliver optimal balance of tensile strength and toughness for demanding diesel exhaust applications
• Black oxide exhaust spacers maintain proper bolt length to ensure fasteners operate within their elastic stretch range, preventing permanent yield or fracture
• Non-zinc-plated construction eliminates the risk of zinc embrittlement that causes premature corrosion failure on coated hardware
• Black oxide coating provides corrosion resistance while matching BD exhaust manifolds aesthetically

Complete Hardware Kit Includes:

• 12 flange head exhaust bolts (M10x1.5 - 60mm, Grade 10.9)
• 12 black oxide exhaust spacers
• 2 stainless steel socket bolts (M10x1.5 - 35mm)
• 2 stainless steel M10 washers

Application Notes:

• Fits 2003-2018 Dodge Ram 5.9L/6.7L Cummins engines (factory heat shield must be removed)
• Compatible with 1998.5-2002 5.9L Cummins engines
• Will fit 1994-1998 5.9L engines with aftermarket manifolds only (does not fit OEM manifolds)

This is a direct replacement part that meets all emissions requirements and is legal for sale and use in all 50 states, including California. Backed by BD Diesel's 12-month parts warranty.
