Description
Jims USA Big Axle Solid Adjustable Tappet
- Standard solid rollers designed around three working parts
The outer wheel/roller has a 27% greater wall size for less harmonic distortion which offers better tracking of cam lobe
Pin bearings are decreased in size by 12%, which increases RPM for more precise tracking
Axle size is increased 36% and doubles as the inner race, so the pin bearing and complete roller assembly now rotates around the axle instead of an inner race, eliminating all possible movement in and around the axle
