Kibblewhite Precision Machining

KPMI Valves - Kibblewhite Precision Machining

White Diamond®: CNC machined from one-piece forgings of EV8 Stainless Steel or Inconel-751. Electroplated with a 360º anode, to produce an even coat of the highest grade hard chrome finish.

Black Diamond®: CNC machined from one-piece forgings of EV8 Stainless Steel. Black Diamond® proprietary multi-stage process reduces friction, and provides superior resistance to corrosion and wear.

Tensilite®: CNC machined from one-piece forgings of 6AL4V or 6-2-4-2 titanium alloy. Finished with a CrN PVD coating that has a low coefficient of friction, and is impact, abrasion, and corrosion resistant.

KPMI Valve Seats - Kibblewhite Precision Machining

Powdered Metal Seats: Have exceptional thermal qualities, wear resistance and resistance to micro-welding. This material resists corrosion and burning, and is compatible with all types of fuel blends.

Nickel Aluminum Bronze Seats: The product of a two year KPMI R&D effort, this proprietary bronze alloy is designed specifically for use with titanium valves in high performance applications.

KPMI Guides - Kibblewhite Precision Machining

C630 Bronze Guides: Tough and wear resistant with excellent thermal qualities. This bronze alloy allows for tighter clearances than other materials. Creating better valve and seat sealing, as well as superior oil control.

Cast Iron Guides: KPMI R&D has produced a proprietary cast iron blend that thrives in the tough operating conditions of today's engine. KPMI's cast iron provides excellent wear resistance and a superior guide bore finish that is easy on valve stems.

KPMI Springs - Kibblewhite Precision Machining

Advanced Spring Design: Springs are engineered for each specific application using proprietary spring design, simulation, and analysis software.

Premium Ground Chrome Silicon Wire: To insure maximum spring life, springs are heat treated, shot peened and X-rayed at regular intervals to check for inclusions.

KPMI Retainers - Kibblewhite Precision Machining

Heat Treated Steel Retainers: KPMI's proprietary heat treatment process creates a hard outer shell with a non-brittle core, resisting wear and maximizing toughness.

Titanium Retainers: To further reduce reciprocating mass, KPMI offers titanium retainers as an alternative to steel.

High Performance Coating: CrN coating for high performance applications, to decrease friction and improve wear. Available for any application on request

KPMI Seals - Kibblewhite Precision Machining

High Temperature: KPMI Viton® seals operate at a higher temperature than other seal materials.

KPMI Tappets - Kibblewhite Precision Machining

Solid Construction: Machined from aerospace quality solid steel bar stock.

Proprietary Heat Treatment Process: Creates a hard outer shell with a non-brittle core, resisting wear and maximizing toughness

High Performance Coating: CrN coating for high performance applications, to decrease friction and improve wear. Available for any application on request

KPMI Keepers - Kibblewhite Precision Machining

Wide Variety of Styles: KPMI offers radius bead, triple radius bead, and square bead style keepers.

High Tensile Heat Treated Steel: Forged or single point machine

KPMI Valve Adjustment Shims - Kibblewhite Precision Machining

Heat Treated Steel: Ground and lapped to precise heights.
