Valve Black Diamond™ – KIBBLEWHITE (manufacturer part number: 82-82055)

Black Diamond™ exhaust valve designed for demanding quads. CNC machined from a monobloc forging of EV8 stainless steel, it combines lightness and strength to withstand the thermal and mechanical stresses of high-performance cylinder heads. The tulip geometry is optimised through finite element analysis (F.E.A.) and the profiles have been validated on a computerised flow bench to ensure a clean and consistent gas passage.

• Application: Exhaust (quad)
• Tulip angle: 22°
• Head diameter: 1.260" / 32.00 mm
• Stem finish: black Nitroneg coating
• Surface treatment: German process applied at 0.002" with a surface layer of 0.0002" to improve wear resistance and reduce friction
• Manufacturing: United States

The Black Diamond™ valve is aimed at tuners and quad riders looking for a reliable, precision-machined valve that is treated to last. Ideal for Polaris Predator and Outlaw 500 (2006–2007 models listed among common applications). Replace your worn valves with an industrial part designed to withstand intensive use while maintaining controlled exhaust flow.
