Description

The Supertech High Performance Valve Spring Kit is specifically engineered for BMW S58 engines, enhancing valve control and reliability. Compared to stock springs, these offer superior spring rates for improved valve control and greater durability. These kits are sought after by enthusiasts, engine builders, and professional racing teams for their ability to handle high RPMs and ensure proper valve operation. By preventing valve float, these springs help maximize power output while maintaining engine reliability. The product details indicate a weight of 5 lbs and dimensions of 6x6x6 inches, with available options for 75 lbs or 84 lbs spring rates. Installation of this valve spring kit requires the expertise of an engine builder to ensure correct fitment and optimal performance.
