JIMS Tappets — Standard, Solid – 58-85 Sportster

Precision roller assembly built around three working components for consistent valve actuation. 🔧

• The outer roller features a 27% thicker wall to reduce harmonic distortion and improve cam-lobe tracking.
• Pin bearings are reduced in diameter by 12% to allow higher rpm and more accurate tracking.
• The axle diameter is increased 36% and serves as the inner race, so the bearing and roller rotate around the axle, removing all play.
• Manufactured in the U.S.A. 🇺🇸

Designed for durability and exacting performance under demanding conditions.
