About this part

Product Details

This Manley Performance valve spring and retainer kit is built with heat-treated, aerospace-grade titanium retainers that are CNC machined to exacting tolerances. These kits are designed to take the guesswork out of preparing your Nissan RB26DETT engine's valvetrain for high-performance use, especially when you're running aggressive aftermarket camshafts.

The chrome-silicon alloy springs offer exceptional fatigue resistance and high tensile strength, which means they can maintain consistent valve control even at extreme RPMs, up to 10,000 RPM according to the manufacturer. This level of stability is crucial for preventing valve float and ensuring reliable engine operation when you're pushing the limits. The kit includes matched valve springs and retainers, specifically designed to work together for optimal performance.

Note that this specific kit, part number 26175, does not include valve locks. You'll need to source those separately. If you're rebuilding the top end of your RB26DETT and planning for significant camshaft upgrades, this kit offers a well-built solution for the valvetrain.
