Taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, KPMI® has developed ovate wire Beehive style springs that will live and Perform at a high level in Harley Davidson® applications. By coupling these developments with strict KPMI® design protocols and employing multiple design, simulation, and FEA analysis software, we were we able to overcome the torsional stresses unique to ovate wire springs that previously severely limited their operating parameters. KPMI® Beehive Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened. The hardened steel base washers included in these kits are designed to locate the spring and control lateral movement. KPMI® made OEM replacement seals are included for a more complete performance valvetrain solution.

• Progressively wound springs using Kobe super-clean, chrome silicon(CrSi) based wire that is heat treated and shot peened
• Tight-tolerance, FEA-designed hardened steel Posi-Loc™ style upper or titanium retainers to ensure correct assembly height and resist keeper "pull through"
• Heat treated (H.T.) steel basewashers are designed to fit on top of either the OEM or KPMI tophat seals in this kit
• Made in the USA
• Kit uses OEM-style valve keys (sold separately).
• '23-'24 CVO's check valve lift to deteremine compatibility with Kibblewhite Precision Machining Inc. (KPMI®) spring kits.
• Installed Spring Height is 1.580"

Kit Includes:

•  8x Titanium Retainers
