If you are wanting to keep your 5.9L or 6.7L Cummins on the road or track for the long haul, you need to replace your head bolts with upgraded head studs. These head studs have a much higher strength and will not stretch like the factory bolts will.

This will help keep your truck from popping head gaskets. The Thoroughbred Diesel Fasteners Competition Series Head Studs are a Heavy Duty stud designed for moderately built to high performance Cummins engines.
