Brand New Kibblewhite Extreme Heavy Duty Cylinder Head Stud Kit
Yamaha Raptor 660 & 660R
Years 2001 2002 2003 2004 2005
•
Nuts are machined from billet high-tensile steel and heat-treated
• Studs are heat-treated 180,000 PSI aircraft alloy steel
• Both nut and stud have rolled threads for the strongest possible threads
• Both nut and stud are black oxide treated for enhanced corrosion resistance
KPMI® Cylinder Head Studs are made from 180,000 psi yield strength, fine grain,
heat treated, aircraft grade alloy steel. When you want a stud that meets
proof-stress and maximizes clamping force, look no further. KPMI® “rolls” the
threads, heat treats, and then centerless grind the entire body of the stud.
Rolling the threads creates the toughest and strongest thread possible and
centerless grinding removes notch sensitivity. The final process for all KPMI®
Studs is to encase the entire stud with a premium corrosion-resistant treatment
of Black Oxide. Congratulations on purchasing a stud that meets
and exceeds your stock-replacement of high-performance needs!
KPMI® nuts are single-point machined from high tensile strength Aircraft Alloy
Steel. During the machining process, close tolerances and smooth surface
finishes are maintained. Two critical factors for achieving correct fit and
torque. After machining, the nuts are heat-treated to a specific depth. This
creates hard, wear-resistant working surfaces while retaining a ductile core
to prevent cracking under load. The premium black oxide treatment provides
excellent corrosion resistance and appearance.
BRAPPPPPPPPPP!
