Typical aftermarket exhaust manifold bolts are shorter than stock. After many heat cycles, they can fatigue, stretch, and cause exhaust leaks or breakage after repeated re - torquing. The finish and coating on most bolts can lead to premature corrosion and zinc embrittlement. Upgrade to BD's class 10.9 bolts and black oxide spacers. These improve thermal durability to handle the heat, and non - Zinc plated fasteners prevent zinc embrittlement.

BD Diesel Part Number: 1045982

Features

• Grade 10.9 hardware balances high strength and toughness
• Exhaust spacers let the fastener stretch elastically without breaking or yielding permanently
• Black Oxide coating matches a BD manifold
• Non - Zinc - plated fasteners stop zinc embrittlement
• Comes with 12 flange head exhaust bolts (M10x1.5 - 60mm 10.9)
• 12 black oxide exhaust spacers
• 2 stainless steel socket bolts (M10x1.5 - 35mm)
• 2 stainless steel M10 washers

Notes

• For 2003 - 2007 5.9L, remove the factory heat shield
• Fits 1994 - 1998 5.9L with aftermarket manifold, not OEM manifolds

This exhaust manifold bolt and spacer kit is designed for 1998.5 - 2018 Dodge Ram trucks with 5.9L and 6.7L Cummins engines. To use it, first, if you have a 2003 - 2007 5.9L engine, you need to remove the factory heat shield. For 1994 - 1998 5.9L engines, make sure you have an aftermarket manifold as it won't fit OEM ones. Then, replace the old, damaged or corroded exhaust manifold bolts with the ones in this kit. The kit includes grade 10.9 hardware which is strong and tough, and exhaust spacers that help the fasteners work properly. The black oxide coating on the spacers matches the BD manifold. The non - zinc - plated fasteners prevent zinc embrittlement. As for maintenance, keep an eye on the bolts for any signs of wear or corrosion. If you notice any issues, check the tightness of the bolts. If they are loose, re - torque them carefully. With proper use and maintenance, this kit will serve you well and keep your exhaust system in good shape.
