KIBBLEWHITE - 30-33600 - Lightweight Racing Valve Spring Kit - '18-'21 Honda CRF250RX, CRF250R
High-lift cams push stock valve springs past their limit, and Kibblewhite's Lightweight Racing kit gives a '18-'21 Honda the spring rate to keep up. It's compatible with boosted or turbocharged applications and is designed with increased spring rates and high-lift compatibility compared to the stock springs. CNC-machined titanium or heat-treated steel retainers paired with Cr-Si (chromium silicon) alloy dual springs keep the valvetrain under control at high rpm and support use with a high-performance camshaft. Made in the USA.
