Gear Down and Go Big
You like to get wild on your Polaris RZR 900, but are you getting as wild as you could? Take the reins off your ride with SuperATV’s 8" GDP Portal Gear Lift. With 8 inches of extra ground clearance and a torque-boosting 45% or 60% gear reduction, you can go places nobody else can.
GDP—the Most Trusted Name in Portals
More riders roll on GDP portals than any other portal system. They’re trail-proven and built for hard riding.
Perfect for Mud
A big lift plus a 45% gear reduction equals a mud-munchin' monster. With clearance for huge tires and plenty of torque to turn them, you’ll cruise over deeper mud and push through anything. Or choose a 60% gear reduction that lets you turn the biggest tires like stock.
A Gear Reduction That Protects Your Drivetrain
GDP puts the gear reduction in the hub instead of in the transmission. Because it comes after your drivetrain, it reduces stress on your axles, differential, prop shaft, and transmission.
Unmatched Gear Material
The gears are made from precision-ground 9310 alloy steel for a quiet, smooth-running portal system.
Stronger Housings by Design
Available with cast aluminum or USA-made billet aluminum housings, with reinforced design and improved oil flow in mind.
- Reinforced in all the right places
- Built with better oil flow and gearing forces in mind
- No vents
The Strongest Portal Backing Plates You Can Get
GDP uses an advanced steel alloy backing plate with 5/16" thickness, hand-welded gussets, and pivot blocks.
Advanced Gaskets and Seals
- Advanced oil-resistant gaskets
- Rubber O-rings that seal the housings
- Sealed input gear and double-lipped output seal
- 100% sealing coverage to help prevent oil leaks
Bearings That Rock
A double-angular contact bearing on the output shaft is designed to handle hard impacts from jumps, logs, and mud holes.
Universal Hubs and Slotted Rotors
Precision-ground stainless steel slotted rotors help keep braking power consistent. Universal hubs and lugs support multiple bolt patterns for a wider wheel selection.
Reinforce Your UTV with a Frame Stiffener
A frame stiffener is highly recommended with these 8" portals to help support your RZR 900 frame.

Polaris RZR 900 Portal Gear Suspension Recommendations
- Max tire size: 34" with stock suspension
- 35" tires require a 2" lift kit
- 48" tires require a 7-10" lift kit
Gear reductions listed are general guidelines to maximize torque and maintain factory top speed. Max tire sizes are measured at full compression and full turn. The given tire sizes are the largest fit without rubbing. With minor trimming or a small amount of rub, larger tire sizes can be used.
Wheel Requirements:
- 22" or larger wheel required
- Wheels cannot exceed 5" backspacing
- Wheels need a center hole of at least 3.25" (82.55mm) or require a 1" wheel spacer
