Polaris RZR Trail S 900 4" Portal Gear Lift

4" portal gear lift built for the Polaris RZR Trail S 900 Sport. 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.

Features:

• Our 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
• There are no gimmicks and no vents because vents do more harm than good—we know because we tested them
• 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
• Available with billet or cast aluminum housing
• Dual idler gear configuration maximizes strength
• Cool, quiet, precision-ground gears made from 9310 alloy billet steel
• 1.5 in. diameter 4340 hardened steel drive shaft
• Housings use advanced gaskets or O-rings that don’t let anything through
• Universal hub fits all major bolt patterns
• Gear reduction reduces stress on your drivetrain
• Dual idler gear configuration adds a 1” offset
• Lighter than the competition
