JIMS Tappets — Oversize (+0.005 in), Solid – 58-85 Sportster

These tappets are engineered for precise cam-lobe tracking and long service life. 🔧

• Standard rollers are designed around three working parts for reliable performance.
• The outer roller features a 27% larger wall thickness to reduce harmonic distortion and improve cam contact.
• Pin bearings have been reduced in diameter by 12% to allow higher rpm and more accurate tracking.
• The axle is 36% larger and functions as the inner race, so the bearing and roller assembly rotate around the axle, eliminating any play.
