Our new Summit 600 ETEC clutch kit is now available. You asked and we deliver. This kit includes our HRSS2 ramps, HRSS helix, primary spring, secondary spring, Hot Rod Sled Shop adjustable pin kit, and QRS Slickshift bearing. This is a dual elevation kit that can go from sea-level to 10k with just pinweight changes. This kit backshifts faster than stock, pulls harder than stock, makes more track speed, and the sheaves run cooler. Our kit engages smoother and lower than stock and also holds back more on descents. This kit makes the 600 a giant killer!
