Tappet Conv Kit,Hi Performance Shovelhead 1/2"Od 6061-T6 Air- Craft Alum Tubing Mfg 6600-R
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. Available 1/2 O.D. 6061-T6 aircraft aluminum and 7/16 O.D. 4130 aircraft Chrome-MolyHARDWARE
