Why Replace the Factory Head Bolts?

Stock head bolts can stretch when exposed to high boost, which often results in blown head gaskets, reduced compression and unexpected repairs. Gator HD220 Head Studs solve this issue by delivering stronger, more consistent clamping force for daily use, heavy towing or high-power builds.

Enhanced Strength. Maximum Performance. Zero Risk.

Take your Cummins further than stock allows. Tow heavier loads, push bigger tunes and avoid leaks or failures. HD220 Head Studs replace weak factory bolts with dependable clamping force, ensuring your engine stays sealed and performs under extreme conditions.
