Jims Fat 6 Super Gear Kit — 6-speed transmission, black end cover

High-performance drivetrain upgrade engineered for increased load capacity and durability.

Straight-cut teeth are 53% wider than stock, allowing additional load capacity and improved strength.

Assembled into a billet aluminum trap door with a large bearing to minimize flex under high-performance use.

Quick-shift ring technology smooths engagement and reduces the annoying clunk during shifts.

Ratios closely mirror stock gearing and retain a 1:1 final drive for a familiar feel.

Lightened one-piece shift drum and aerospace-grade 9310 construction provide exceptional strength and toughness.

Drop-in installation — no case or exhaust mount modifications required for most setups.

Note: some '06–'09 indicator lights may require a technician flash for full functionality.

Built in the USA and assembled in a technologically advanced facility.
