Black Diamond™ Valve Kit — Manufacturer's ref: 20-22300
Designed for Roadster engines, this KIBBLEWHITE Black Diamond™ valve kit offers reinforced replacement parts for demanding cylinder heads. Each valve receives a special surface treatment to a depth of .002”, with a finishing layer of .0002”, a process that enhances wear properties, reduces friction, and provides better resistance to corrosion and abrasion. Compatible with leaded and unleaded fuels. Made in the USA.
Ideal for restorations and maintenance on vintage Roadsters, particularly Harley-Davidson Sportster XLX/XLS/XLH 1000 (1983). Prepare your cylinder head, check the seats and the fit before installation to ensure optimal performance.
