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 Diesel class 10.9 bolts and spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement. Order the kit recommended for your vehicle and engine application. BD Diesel exhaust manifold bolt and spacer kit #1041483 details: * Exhaust spacers ensure fastener operates in elastic stretch without fracture or permanent yield * Class 10.9 hardware * Non-zinc plated fasteners prevent zinc embrittlement * Includes 16 exhaust spacers (18mm) * Includes 16 flange head exhaust bolts (M8x1.25 – 40mm 10.9)

On certain Ford trucks and vans, the original equipment studs connecting the catalytic converter to the exhaust manifold flange can typically rust and break, and removal can be difficult, but Dorman has an OE FIX. Their exhaust flange repair kits offer a cost-effective, faster, and much simpler way to securely reconnect the converter and flange using ordinary hand tools, and without drilling, heating, or welding. Dorman exhaust manifold flange repair kits contain a pair of sturdy stainless steel brackets designed to fit over the broken stud sections on the manifold flange, and feature an integrated threaded stud that slides through the catalytic converter mounting holes. Just push the threaded end of each bracket through the catalytic converter mounting holes, place the contoured side of each bracket against the exhaust flange and around the headless broken studs of the exhaust flange, and secure the connection with the included stainless steel nuts. Make flange repairs without the high cost and labor of replacing the complete pipe. Select a Dorman kit for your OE FIX.
