Description
The Kibblewhite Racing Valve Spring Kit is engineered to provide exceptional valvetrain control, even under the most demanding conditions. These kits are perfect for engines running high-performance camshafts and those with increased boost levels. The increased spring rates and high lift compatibility, up to 0.440", offer a significant advantage over stock springs. CNC-machined titanium or H.T.
