If you are wanting to keep your 6.2L or 6.5L Chevy/GMC Diesel on the road 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.

These Gator Fasteners Performance Head Studs are a Heavy Duty stud designed for stock to moderately built Duramax engines.
