S&S CYCLE GUIDE VALVE C.I. 84- 90-2210

Valve guide wear is one of the fastest ways to lose compression and increase blow-by in your Harley engine—and once they're shot, no amount of tuning will bring back the performance you've lost. The S&S Cycle Guide Valve is a direct replacement engineered to restore proper valve sealing and clearance, giving you the precision fit that stock replacements simply can't match. Cast from high-quality iron and manufactured in the U.S., this guide is built to handle the demands of both street and competition engines.

Whether you're rebuilding S&S Super Stock heads or restoring a stock Harley-Davidson cylinder, this guide delivers the bore consistency and material thickness required for proper valve action and longevity.
