Description
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 spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement.This Part Fits:YearMakeModelSubmodel2004-2007FordF-250 Super DutyHarley-Davidson Edition2004-2007FordF-250 Super DutyKing Ranch2003-2007FordF-250 Super DutyLariat2003-2007FordF-250 Super DutyXL2003-2007FordF-250 Super DutyXLT2004-2007FordF-350 Super DutyHarley-Davidson Edition2003-2007FordF-350 Super DutyKing Ranch2003-2007FordF-350 Super DutyLariat2003-2007FordF-350 Super DutyXL2003-2007FordF-350 Super DutyXLT
