Lighter than the competition
What is a dual idler?With two idlers in the portal box, the load gets spread over two gears instead of one. The gears are precision CNC ground and made from 9310 steel alloy for strength and even force distribution.
Ride anywhere you want with 15% and 30% gear reductionsChoose a 15% reduction for boosted torque with more top-end speed, or a 30% reduction for maximum torque and acceleration, ideal for mud, rocks, and big tires.
A gear reduction that protects your drivetrainBecause the gear reduction is in the hub, it helps reduce stress on your axles, differential, prop shaft, and transmission so you can ride harder with less wear.
Stronger housings and backing platesChoose a cast or USA-made 6061 billet aluminum housing with advanced steel alloy backing plates. The housings are reinforced for gear retention and optimized for oil flow, and there are no vents.
