These CYLINDER BEARINGS by POWER CUSTOM are designed to reduce cylinder and yoke endplay in Smith & Wesson J Frame centerfire pistols.
The bearings are made of hardened 302 stainless steel, providing a high-quality option for rebuilding or customizing firearms.
Each pack includes 10 bearings that are .002" (.051mm) thick, ensuring a precise fit and a professional-grade finish for the gun.
These stainless steel gas ring shims are designed to eliminate excess cylinder endshake in Colt and clones, as well as all Ruger® single action revolvers.
The shims, with a thickness of .0045", prevent cylinder binding and help resolve headspace issues that can cause misfires.
Developed by Ron Power, the shims are a cost-effective solution compared to stretching the gas ring and are suitable for both repair and custom gun builds.
