VALVES

and

SPRING KITS

Black Diamond™Valves:

All KPMI Black Diamond™ stainless steel valves are impregnated by a special German process

to a depth of .002”, with a surface build up of .0002”. This “Black Diamond™” process improves wear

properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and

nickel electrolysis plating. Black Diamond™ Valves are light, strong, one-piece forgings with profiles that

provide excellent flow characteristics.

White Diamond™Valves:

We fully CNC machine our White Diamond™ Valves from a one-piece forging of either EV8 Stainless Steel

or Inconel -751. These materials have proven heat and corrosion resistance properties. A 360-degree anode

is used to produce the highest possible grade of hard chrome finish.White Diamond Valves are light, strong,

one-piece forgings with profiles that provide excellent flow characteristics.

KPMI Tensilite® Titanium Valves:

• KPMI® Recommended OEM Replacement Valves

• Exceeds OEM Specifications

• Your OEM Alternative

• Compatible with O.E.M. Spring Kits

If you look closely at the KPMI® Tensilite® titanium valves, you will notice the U.S. milled one piece forged

design, precision ground stems and the CrN PVD coating covering the entire valve. In cases where the OEM

uses steel exhaust valves, KPMI® has elected to implement our race proven line of Black Diamond™ stainless

steel exhaust valves, rather than create a new line of valves made from a lesser quality material to match the

OEM. For your next factory rebuild, upgrade to KPMI® and gain yourself some performance and reliability,

while saving yourself some money.

Note: These valves are intended as O.E.M. replacement valves and are completely compatible with the O.E.M.

spring kits. However, experienced engine builders, who are running aggressive camshafts or higher than

factory RPM’s may find the combination of the O.E.M. Style Valve and KPMI’s Lightweight Racing Spring Kits

advisable.

KPMI Valve Springs:

KPMI® valve springs are wound from Premium Kobe Super-

Clean Chrome Silicon Wire. KPMI® valve springs are heat-

treated, stress relieved, and shot peened to insure maximum

performance and life.Springs are engineered for each specific

application using proprietary advanced spring design simulation,

and analysis software. Engineers pay special attention to cam

and spring harmonics, stress, mass, and operating rpm.
