Beschreibung

These tappet kits for Panhead and Shovelhead motors are capable of the highest RPM a Harley can safely run at a valve lift of up to .700" in combination with the right valve springs, valves and cam. The use of these hydraulic tappets enables Panhead and Shovelhead motors to have all the hydraulic benefits of the late Evolution style hydraulic system, as they will eliminate the total oil loss of the old style hydraulic units. The billet tappet blocks are made from 7075-T651 with a tensile strength of 83,000 psi which is almost triple the amount of cast tappet blocks. Fits Panheads 1953 thru 1964 and Shovelhead from 1965 thru 1984. Do not use the early tapered 1/4"-24 screws on these blocks unless you provide a counter sunk for that style screws.

Note: These blocks are designed to accommodate a gross valve lift of .550" at the valves. This is about .350" at the tappets, leaving a clearance of .035" roller to block free play. If used with higher lift cams tappets must be modified. Use with standard pushrods or equivalent to standard pushrods.
