Stage X Extreme 11mm Cylinder Head Stud Kit

The Stage X Extreme 11mm head stud kit is a must for a performance build.

Made from aircraft-grade S99 steel with a tensile strength in excess of 237,000 psi (1640MPa), this 11mm kit reduces head movement under boost and provides optimum head-to-block clamping, dealing with the higher combustion pressures of a modified performance engine.

This kit is a direct fit into the standard block assembly, with no modifications required.

Supplied with graphite-based assembly lube, so the correct torque figures can be reached accurately.
