Your Can-Am Defender HD8 isn't a powerhouse until it has SuperATV's 6 Portal Gear Lift installed. This means more torque and bigger tires without stressing out your Defender. Choose between 30%, 45%, or 60% gear reduction to match your riding style, and for maximum durability, upgrade from SuperATV cast housing to SuperATV billet aluminum housing. Are you looking for even more power? SuperATV dual idler portals are the perfect option for you.
What Is a Dual Idler?
Perfection takes time. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don't do a thing if they're not mated perfectly, though.
Get the Power to Conquer Any Terrain
A gear reduction changes how your ride performs on different terrain. Choose 30% for faster speeds with plenty of torque. If you have larger tires and tackle tough trails, go with 45% to get extra power and control. Construct the ultimate mudder with a 60% gear drop, and maximize its torque by adding dual idler gears.
Protect Your Drivetrain
GDP Portals relocate the gear reduction to the wheel hubs instead of the transmission. This reduces stress on your Defender HD8s drivetrain, letting your axles, driveshaft, differential, and transmission work less, which lowers wear and helps prevent costly repairs.
Unmatched Strength
Durability matters.
- SuperATV housings are reinforced for gear retention and optimized for oil flow
- Advanced steel alloy backing plates are stronger than chromoly
- Enhance with Portal Blood - gear oil formulated for GDP Portals
Advanced Gaskets, Seals, and Bearings
SuperATV portals use:
- Advanced gaskets and O-rings with excellent oil resistance and low deterioration rates
- A sealed input gear and double-lipped output seal
- 100% sealing coverage throughout so you can forget about oil leaks
- Double-angular contact output bearings to prevent premature wear
- Roller idler and drive bearings to maintain perfect gear meshing
Don't Forget a Frame Stiffener
Monster tires and portals bring the fun - but they also stress your machines frame.
