KIBBLEWHITE Valve Guide - Big Twin 20-2064

Valve guide wear is one of the most overlooked sources of oil consumption and performance loss in Big Twin engines. The KIBBLEWHITE 20-2064 addresses this directly with precision engineering and material science that simply outlasts OEM guides. If you're rebuilding a top-end or fighting excessive blow-by, this is the upgrade that delivers measurable results.

KIBBLEWHITE's nickel bronze construction isn't marketing speak—it's material selection backed by decades of racing application. The 5% nickel content and 80% copper blend creates a guide that resists the thermal cycling and abrasive wear that destroys lesser alternatives, while maintaining the heat dissipation your valvetrain demands. These guides are compatible with modern no-lead fuel and work with any valve-stem material, making them the right choice for both restorations and modern performance builds.
