Designed as a gear drive kit for Big Twin applications, it features an Easy Start compression release that temporarily reduces crank compression during starting, then retracts as rpm increases so the engine runs normally— with full compression and no performance loss . Key Features Easy Start : reduces crank compression to help starting, then centrifugally retracts for normal operation Optimized for Softail & Dyna (great overall camshaft for Big Twins) Strong low-end torque and horsepower Strongest 1500–5000 rpm in Softail and Dyna models Bolt-in kit for streamlined installation Made in the USA Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread lock, and instructions Fitment Notes Installer must check coil bind , valve-to-valve clearance , and valve-to-piston clearance .
