KIBBLEWHITE - 20-22800 - Black Diamond™ Engine Valve Kit - '88-'03 Harley-Davidson Sportster 1200 Custom, Sportster 1200 Sport, Sportster 1200
For a '88-'03 Harley-Davidson valve job done as a complete set, 20-22800 is Kibblewhite's Black Diamond engine valve kit, every valve treated with the same .002-inch-deep surface hardening process that reduces friction and boosts wear and corrosion resistance beyond an untreated valve. That consistency across the full set matters when the goal is even seat wear and predictable valve lash down the road. Runs on leaded or unleaded fuel. Made in the USA.
