Quick Ship SKU #: BD-1045982 BD 1045982 Exhaust Manifold Bolt & Spacer Kit 98.5-18 Ram 5.9L / 6.7L Cummins

Replace and upgrade your exhaust manifold bolts with this black oxide 10.9 grade bolt and spacer kit for your 1998.5-2018 Cummins truck. Typical aftermarket exhaust manifold bolts are much shorter than stock which after numerous heat cycles can cause them to fatigue and start to stretch, leading to exhaust leaks and possible breakage after repeated re-torques. The finish and coating on most of these bolts can also lead to premature corrosion and zinc embrittlement. Replace damaged or corroded exhaust manifold bolts with BD's class 10.9 bolts and black oxide spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement.
