HARDWARE HI-PERFORMANCE TAPPET CONVERSION KITS FOR SHOVELHEAD

WEIGHT: 0.83
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-MOLY
