Nice pieces. Slapped them in while I had the head off for stage 3 piston install. Went in smooth. No complaints!
Top notch great company to do business with and always the best shipping time hands down.
After years of not locating the ultimate valve spring, we decided to have our own made. These springs can handle 12k+ RPM with any camshaft available and have been designed to not need an inner spring in order to keep valvetrain weight low. Compatible with the stock retainers.
Fits: 2022+ Honda Grom/Monkey
