H. T. Steel Basewashers
• These springs have been designed to provide pressures to control stainless steel valves. Experienced engine builders who are running aggressive camshafts
or higher than factory RPM's may choose to run these elevated pressures with titanium valves as well
• These high quality replacement springs have been designed to exceed the OEM speci昀椀cations by 昀椀tting precisely on the spring shoulder diameter of both the
OEM retainers, and KPMI H.T. Steel retainers (P/N 60-60941)
• This kit also includes H.T. Steel basewashers in order to achieve a precision 昀椀tment on the large end of our beehive spring which, better controls the lateral
motion of the spring, ensuring longer life and less wear on the spring, retainer, and basewasher.
• KPMI® has gone a step further and speci昀椀ed the latest in spring materials and processing, for an extremely robust design that will last longer than anything
currently on the market
• Unique features of this spring include is beehive variable rate wind to reduce the chances of spring surge due to cam harmonics, Super-Clean Chrome Silicon
wire with additional Vanadium and Nickel added for increased strenth, and a gas nitrided and double shot peened 昀椀nish for greater fatigue life

• By utilizing FEA software, it was possible to take advantage of the increased strength and wear resistance of a heat treated steel retainer, while reducing its
mass to within grams of a comparable titanium retainer
• These retainers are intended as an OEM replacement and are completely compatible with the OEM springs, keepers, and shims
• The spring shoulder diameter has been designed to match the OEM retainer and spring as well as KPMI's beehive spring (P/N 60-60950), making this retainer
your high performance OEM alternative
