FEULING PARTS Rocker Shaft Shims — 24 pack – 18-26 Softail, 17-26 Touring, 17-25 Trike, 17-25 CVO

Quiet your engine by tightening the rocker arm to cylinder head end play clearance. The manufacturer recommends an ideal side clearance of 0.0035” - 0.005” for optimum rocker arm oil psi and noise reduction.

M8 cylinder heads can develop excessive wear on the rocker arm standoff thrusting surfaces. When the hardened shim is placed on the thrusting side it helps reduce further wear and damage to the cylinder head.

• Made in the USA 🇺🇸
• These shims should be installed by a professional who can make correct end play measurements and tighten rocker shaft nuts/bolts without damaging the shims

Use these shims to restore correct end play, improve oil pressure to the rocker arms, and reduce noise and long-term cylinder head damage. 🔧
