Studs / Gaskets Combos

Head Stud & Gasket Kits for Diesel Engines
When you’re doing a head gasket repair on a diesel truck, the gasket and the clamping hardware need to work together. Running a high-spec MLS gasket with stock torque-to-yield head bolts is a common mistake — the gasket can outlast the hardware that’s supposed to hold it in place. Our stud and gasket combos take the guesswork out of matching hardware to sealing strategy.

We offer matched kits for Powerstroke 6.0L (18mm and 20mm), Cummins 5.9L 12-valve and 24-valve, Cummins 6.7L, Duramax 6.6L L5P, and other platforms. Kits range from solid seal setups with standard studs for towing and daily-use builds to 240ksi stud combos for performance and high-boost applications.

Why buy a combo kit instead of parts separately?
The gasket thickness, stud tensile rating, and torque spec all affect how the sealing system performs under load. Pairing an oversized gasket with undersized clamping hardware — or vice versa — creates a mismatch that shows up as a repeat failure. Our combo kits are matched by application so the components work as a system, and they ship together so you’re not waiting on two separate orders when the truck is already down.

Solid seal kits combine our premium gasket with a matched stud set for complete upper-end hardware replacement in one box. Available for most platforms with standard and 240ksi stud options depending on build level.

Fire ring combos pair our fire ring gaskets with compatible hardware for high-boost Cummins builds where maximum combustion sealing pressure is the priority.
