4"” portal gear lift built for the Can-Am Defender HD11. It adds lift at the wheel hubs and puts the gear reduction in the hub, so you get ground clearance and extra torque without asking more of the drivetrain behind it. Choose a 15% or 30% gear reduction and cast or billet aluminum housings to set the kit up for the riding you do, with single or dual idler gears on the versions that offer them.
Choosing your setup: Single idler is the standard setup; dual idler adds a second idler gear in each portal box, spreading the load over twice the gear surface for the strongest gear set SuperATV makes — dual idler kits come in billet housings only. Cast housings keep the price down, while billet housings are machined from solid aluminum for maximum strength. On gear reduction, a higher percentage gives you more torque for turning bigger tires in mud and rocks at the cost of some top speed, while a lower percentage keeps more top-end for trail riding. The frame stiffener option adds SuperATV’s frame stiffener kit (+$205.95) — worth adding on machines that will see hard use with big tires.
