FEULING PARTS Compensator & Primary Drive Sprocket This replacement spring is engineered to reduce excessive compensator travel, thereby lowering harmonic vibration and smoothing engine start‑up. The steeper bevel design increases preload on the spring pack and compensator, delivering a more responsive feel at lower engine RPMs. Compared to the stock unit, the FEULING spring is thicker, stronger, and features an increased bevel, providing greater durability and performance. It replaces the first, outer‑most spring in OEM pack 83936‑09A and is compatible with 2007‑2012 Twin Cam models (including 2006 Dyna) that have been fitted with the updated Screamin Eagle compensator.
