The BD Diesel exhaust manifold bolt and spacer kit for 2003–2007 Ford F250/F350 6.0L PowerStroke includes 16 flange-head M8x1.25 40mm class 10.9 bolts and 16 18mm spacers to restore proper fastener stretch and reduce failure. Non-zinc-plated hardware prevents zinc embrittlement and improves thermal durability versus shorter aftermarket bolts, helping prevent exhaust leaks and premature fastener fatigue under heat cycling.
