Jims Powerglide Steady Roll Tappet .002 Oversize

Jims powerglide steady roll tappets feature a special bronze alloy roller bushing in place of stock type loose needle roller bearing.
As an added bonus to increased reliability and longer life, it's quieter operation is due to the tighter tolerances this design allows. This failsafe design means even if the bushing wears out, it will be retained in the tappet assembly. Measures 0.8475".
