By 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.

Note: Maximum Recommended Lift = .610in.

Installed Height: 1.860in.

Seat Pressure: 175#

Open Pressure: 400#

Tech Tips:-

* Rocker box clearance must be checked

* Spring travel must be checked

* Valve timing must be accurate

** Over revving will lead to pre-mature failure of Valve Springs & collars.

Feuling 585in. Lift ECONO Performance Beehive Valve Spring Kit. Fits Twin Cam 2005-2017 & Sportster 2004-2021.

Raegun — Tue, 26 May 2026 09:50:05 +0000

FEULING ECONO performance BEEHIVE valve springs designed to handle up to 585 lift camshafts at an economical price. These FEULING BEEHIVE springs are made from the same premium stress relieved conical ovate wire as our HIGH LOAD springs but are developed for economical engine budgets. They have an excellent level of fatigue life and are designed to handle the demands of performance engines with 585 and smaller lift camshafts. Dyno proven and track tested.

FEULING BEEHIVE valve springs use a much smaller and lighter weight retainer which drastically reduces the valve weight creating a much quicker revving and smoother motion than comparable dual valve springs.

Kits include: FEULING ECONO BEEHIVE valve springs, lightweight steel retainers, machined heat treated chrome moly spring seats, seat shims, valve locks and a set of premium Viton valve seals equipped with a spring loaded valve stem wiper system.
