Get your engagement up for a hard launch with or without Launch Control! The EVP Lime Green spring is made from the finest chrome silicon steel alloy which is superior to other alloys. Most UTV primary clutch springs are made from “music wire” which has a higher sag rate and cannot withstand the constant cycling that chrome silicon can. The EVP Lime Green spring was designed to work with the existing XP Turbo clutch kits with a finish rate similar to EVP Red and Blue springs. The lime green spring will raise your clutch engagement 200-400 rpms higher than the Blue or Red springs.
