GSC Power-Division P-D Beehive Valve Spring and Titanium Retainer Kit for BMW Z4 & Toyota Supra B58 (MPN 5091)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits BMW Z4 and Toyota Supra models equipped with the B58 engine.
The GSC Power-Division (P-D) Beehive Valve Spring and Titanium Retainer Kit is engineered to handle the increased valvetrain stress associated with high-performance B58 builds. By utilizing a beehive-shaped spring design, this kit offers superior harmonic resistance and reduced reciprocating mass compared to standard cylindrical springs. This is a critical upgrade for preventing valve float at high RPMs and under the elevated boost pressures common in tuned applications.
The included CNC-machined titanium retainers significantly lighten the valvetrain assembly, improving engine response and overall reliability during aggressive driving or track use.
- Engineered specifically for the B58 engine platform
- High-tensile beehive valve springs for improved harmonic damping
- Lightweight CNC-machined titanium retainers to reduce valvetrain mass
- Prevents valve float in high-boost and high-RPM applications
- Manufacturer Part Number: 5091
