Feuling Beehive High Load Valve Springs For Harley Twin Cam / Sportster 2004-2022

Feuling Beehive High Load Valve Springs For Harley

Feuling® High Load premium performance Beehive® valve springs are designed for steep ramped large lift camshafts. These valve springs are made from premium stress relieved conical ovate wire with a nitrided surface heat treatment, shot-peened surface enhancements along with a Nano Peen™ polish. They have an extremely high level of fatigue life and are designed to handle the highest demands of performance engines with high lift, steep ramped camshafts. 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. Dyno proven and track tested.

• Allow up to 750 lift cams
• No rocker box clearancing required
• Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
• Don't get stung by inferior valve springs!
