Nissan SR20 Head Stud Kit

The Nissan SR20 Head Stud Kit from OPTITORQUE TECHNOLOGIES LLC is designed for automotive builders and enthusiasts who require maximum reliability in high-boost or high-RPM engine builds. This kit replaces factory bolts with head studs to mitigate the risk of head lift and gasket failure, making it a vital upgrade for any SR20 platform undergoing significant performance enhancements.

Engineered to provide superior clamping force, the head studs in this kit ensure that the cylinder head remains sealed under extreme conditions. Unlike factory bolts, head studs experience pure tension rather than shear stress, which allows for more consistent clamping loads across the entire deck surface. The kit is precision-manufactured to OEM specifications, ensuring proper bore alignment and even load distribution, while premium materials prevent bolt stretch and relaxation.

Ideal for those rebuilding an SR20DET, SR20VE, or SR20DE engine intended for forced induction or high-compression configurations, this kit is essential for achieving optimal performance. Proper installation requires removing the cylinder head and utilizing a torque wrench to follow the correct torque sequencing, which helps eliminate hot spots and uneven gasket compression that can lead to failures in modified applications.
