KyVex Billet Cush Jack

Every time power hits or drops away, the stock rear sprocket hub takes the shock — and on a high-power build, that punishment adds up fast. Chain, sprocket, and jackshaft all pay the price. The KyVex Billet Cush Jack stops the damage at the source.

CNC-machined from solid 6061 billet aluminum, it replaces the stock hub with a precision component built to soak up the rotational shock of acceleration and deceleration. The payoff: smoother power delivery, less drivetrain wear, and a quieter, more controlled ride — exactly where stock parts were never meant to keep up.

Installation is pure bolt-on. No modifications, no fabrication, no specialist tools — it drops in right where the stock piece came out, lined up to factory spec.
