BMW N54 Conical Valve Spring kit by SuperTech
Engineered for reliable valve control, RPM stability, and long-term durability.
Conical valve springs taper from base to top to significantly reduce retainer/spring mass, improving harmonic control and valvetrain stability at high RPM.
Supertech valve springs are manufactured from premium Chrome Silicon alloys and heat-treated for fatigue resistance, while the included titanium retainers reduce valvetrain mass to improve control at higher engine speeds.
Features-
Conical spring design reduces mass for improved RPM capability
Titanium retainers for lightweight, high-strength valvetrain support
Enhanced harmonic control for stable high-speed valve motion
Matched spring set for consistent pressures and performance
CNC-machined components for accurate fit and reliability
Benefits-
Maximum RPM stability through reduced valvetrain mass
Improved control for aggressive cam profiles and track use
Reduced valve float risk under high-speed conditions
More durable valvetrain operation under stress
Race-proven performance characteristics
