Lock Down Your Duramax Before You Turn Up The Power

If you're planning to push your 6.6L Duramax with a tuner, bigger turbo, or serious towing loads, you need head studs that can handle the pressure. The PPE-288 High Yield Head Stud Kit gives your engine the strength it needs to hold everything together when the boost is cranked up and temps are running high. With a tested tensile strength over 280,000 PSI, this kit is built for the kind of abuse stock bolts just can’t take. It’s the kind of upgrade that prevents head gasket failures before they start, giving you peace of mind whether you're towing uphill or laying into the throttle. PPE includes everything you need in one complete package, 12-point nuts, hardened washers, head bolts, and a packet of assembly grease to ensure even clamping across all cylinders. You’ll feel the confidence in every pull, knowing your engine has the reinforcement it needs. For any serious Duramax owner, this is one of those upgrades you do once and never look back on.

Precision Built To Handle Heat Boost And Load

The PPE 118034350 High Yield Head Stud Kit is engineered for durability and clamping performance under the most demanding conditions. Built specifically for 2001-2016 GM 6.6L Duramax engines, these studs are made from PPE’s proprietary PPE-288 alloy, delivering over 280,000 PSI tensile strength and 253,000 PSI yield strength. The ultra-low impurity level in the material enhances fatigue life and reduces the risk of embrittlement under high heat and pressure. Each stud undergoes heat treatment before being centerless ground and thread rolled, processes that improve strength and consistency while minimizing the chance of thread damage. Surface treatment adds another layer of protection to ensure long-term durability in tough environments. The included hardware, nuts, washers, and head bolts, is designed to distribute clamping force evenly and deliver precise torque. This kit is an ideal foundation for performance builds, heavy-duty towing setups, or any Duramax that sees more than just stock power levels.
