16x For Brian Tooley Racing GM LS7 Lifters LS/LQ 4.8/5.3/5.7/6.0/6.2L 12499225💰 For Sale - New and Used

Function:

Hydraulic adjustment replaces the adjustment screw and lock nut. The hydraulic tappet is always in contact with the camshaft, runs without clearance, maintains a reasonable valve volume, and reduces the impact and noise between parts.

Choose the thickness of the tappet: measure the measured value of the gap, the reasonable gap of the valve is 0.20MM and the exhaust pipe gap is 0.30MM, and then the thickness of the exhaust tappet can be calculated.
