When you’re pushing serious boost or spraying nitrous, your engine’s weakest link can be what holds it all together. The cylinder head-to-block seal is one of the most critical interfaces in any high-performance engine, and under extreme pressure, even the best head studs can lose their clamping integrity. That’s where the Straub Sure-Clamp Option for their CNC ported LS and LT heads steps in.

Simple And Effective

Straub Technologies designed this option specifically for high-stress, high-horsepower applications, the Sure-Clamp system goes far beyond your typical head stud washer. Straub starts with 4340 Chrome Moly, a material known for its incredible strength and durability under load. Each washer is precision-machined, case-hardened, and finished with a black oxide coating to provide both superior corrosion resistance and a no-nonsense appearance worthy of a serious engine bay.

But this upgrade is about more than looks—it’s about performance where it counts. The Straub Sure-Clamp washers are engineered to spread the clamping force over a significantly larger surface area around the head bolt holes, which prevents the washers from embedding into softer aluminum cylinder heads. This wider load distribution reduces torque loss during heat cycling and re-torque procedures, providing a more consistent and reliable clamping force across the board.

Keeping Everything Sealed

The result? Heads stay clamped, power stays planted, and your confidence remains high—no matter how hard you’re pushing it. Whether you’re building a boosted LS or a nitrous-fed Gen-V LT, the Sure-Clamp Option provides bank vault-level sealing integrity where it matters most. It’s designed for engines that live under pressure and refuse to back down.

And the best part? You can add the Sure-Clamp Option for just $280 when bundled with any CNC-ported cylinder head from Straub Technologies. That’s a smart investment in long-term reliability without blowing your budget. Don’t let your head studs tap out. Upgrade with the Sure-Clamp Option from Straub Tech and lock it down like your power depends on it—because it does.
