  • Made from ultra high-strength conical-oval chrome-silicon wire, then shot-peened, heat-treated, and finished with Super NexTex® to deliver the longevity demanded by V‑Twin engines, whether stock or performance-built.
  • FEULING® BEEHIVE® valve springs use a more compact, lightweight retainer, dramatically reducing mass on the valve side for faster revs and smoother operation than conventional single or dual springs.
  • Direct replacement valve springs: no spring seat or rocker cover modifications required up to 0.565" lift.
  • Compatible with camshafts providing more than 0.600" lift, provided the spring seat pocket in the head is machined to achieve the correct open height.
  • Smaller, lighter retainers significantly reduce moving mass for quicker revs and more consistent motion than traditional dual or single springs.
  • Design eliminates spring separation, optimizing stability and reducing valvetrain noise and vibration.
  • Kit includes: a matched set of Feuling® High Load Beehive® valve springs, titanium retainers, machined seats, seat shims, valve locks (keepers), and a set of premium Viton® valve stem seals with spring-loaded stem wiper.
