Produce more power and torque in the riding RPM range increasing throttle response, acceleration and fuel mileage.
Wide lobe separations produce wide power bands.
Smooth camshaft lobe ramps are easier on valve-train components and eliminate excessive valve-train noise and wear.
Dyno proven and track tested.
Made in the U.S.A.
Requires performance valve springs.
Performance lifters recommended but not required.
Will work with factory pushrods on engines with factory stack up; if deck height, cylinders or rocker boxes have been modified from stock then adjustable pushrods are required.
