What It Does Dual Idler Gears: Distributes load across twice as many teeth, reducing stress and improving torque transfer.
Perfect for Big Tires: Ideal gear ratio for running 40" tires or larger - helps prevent belt, axle, and drivetrain failures.
Better Engine Braking: 60% gear reduction improves engine braking and reduces brake wear.
More Power, Less Speed: Great for riders who prioritize torque and control over top speed.
Why It Is Better
Forged Gear Boxes: Tougher and more durable than cast or billet aluminum (what competitors use).
Optional Gear Box Venting: Reduces heat buildup, prolongs gasket and seal life.
Kevlar Gaskets: High-density, creep-, oil-, and coolant-resistant”no extra sealant needed.
Triple Seals: Dual spindle seals + wiper seal on input shaft = max protection from water and oil leaks.
Beefed-Up Backing Plate: 5/16" steel with bent flanges and welded gussets for extreme durability.
13" Rotors: Precision-ground stainless steel with slots for cooling and performance.
Strong Gear Profile: Heat-treated alloy steel, CNC-machined, and lapped for smooth, quiet operation.
Future-Proof: Start with a 45% Single Idler Kit and upgrade later to 60% without needing a whole new kit.
