Exhaust Manifold Bolt and Spacer Kit Dodge 5.9L/6.7L Cummins 1998.5-2018

Typical aftermarket exhaust manifold bolts are much shorter than stock, which after numerous heat cycles can cause them to fatigue and start to stretch. This leads to exhaust leaks and potential breakage after repeated re-torques. Additionally, most aftermarket bolts have finishes or coatings that are prone to premature corrosion and zinc embrittlement. Replace damaged or corroded hardware with BD's Class 10.9 bolts and black oxide spacers. These components improve thermal durability and resist the heat. The non-zinc plated fasteners are specifically selected to eliminate the risk of zinc embrittlement.

Features

Grade 10.9 hardware provides a balanced combination of high strength and toughness.
Exhaust spacers ensure fasteners operate in elastic stretch without fracture or yielding.
Black oxide coating matches BD exhaust manifolds for a clean look.
Non-zinc-plated fasteners prevent zinc embrittlement and corrosion-related failures.
Includes 12 flange head exhaust bolts (M10x1.5 - 60mm 10.9), 12 black oxide exhaust spacers, 2 stainless steel socket bolts (M10x1.5 - 35mm), and 2 stainless steel M10 washers.
