Fits: 1966-1984 Harley Davidson Shovelhead Big Twin's with Hydraulic Lifters

Convert your hydraulic tappets which are known to float at high RPM to solid adjustable tappets.

We put the adjuster into the tappet body with a design to increase the stability of the pushrod at greater angles.

A tapered split locknut is used for the best possible way to lock the adjusting bolt into the lifter body.

A 5/16-32 extra fine thread is used for easier and closer adjustments.

All pushrods are long enough to accommodate engines with stroker cylinders.

All wear surfaces are hardened for maximum durability.
