SuperATV HD8 4in. Portal Gear Lift for Can-Am Defender

Ready to tackle tougher trails? The SuperATV 4 Portal Gear Lift for your Can-Am Defender HD8 gives you 6 inches of lift and a built-in gear reduction for more torque and ground clearance. Run larger tires with ease and choose a 15% or a 30% gear reduction depending on how you like to ride. Upgrade from cast to billet aluminum housing for extra strength. For maximum performance, choose SuperATV dual idler options.

What Is a Dual Idler?

Adding a second idler gear spreads the load over more surface area, giving you more reliable torque and a super-strong gear set.

An Option for Every Rider

No matter how you ride, GDP Portal Gear Lifts are ready to deliver. Rip across dunes, blast through trails, crawl through mud, or put in work around the property - there's a portal built for it. Run a 15% gear reduction for speed and fun, or drop down to 30% for max torque and big tire domination. Upgrade to dual idler gears and push your rig harder than ever.

Protect Your Drivetrain

GDP portals shift the gear reduction to the hub, taking stress off the drivetrain where it matters most. As a result, major components - axles, differential, prop shafts, and transmission - are protected from the excessive force required to turn large tires.

Built Tough with Aluminum and Steel

These portals are made to last. With cast and billet aluminum housings and heavy-duty advanced steel alloy backing plates, they're built to handle whatever you throw at them.

• 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

Add a Frame Stiffener

Portals and monster tires push your machine to the limit - and your frame feels it. Ensure maximum durability by installing a SuperATV Frame Stiffener along with your new HD8 portals.
