Feuling FE-1121 585in. Lift ECONO Performance Beehive Valve Spring Kit for Twin Cam 05-17/Sportster 04-21

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 spring kits are each hand measured and labeled specifically based on their coil bind / required open height. Our kits require you to measure installed height and may require use of included shims. This is so you can set up the springs specifically to your camshaft lift for quieter and smoother performance. Similar to tuning your suspension to your weight and riding style.

• 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.
• FEULING® ECONO springs allow up to 585” lift cams, no rocker box clearancing required.
• Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
• Available for 5/16” and 7mm valves

Kits include: FEULING® ECONO BEEHIVE® valve springs, lightweight 7 Degree Ti 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.

Don’t get stung by inferior valve springs!
