Gear Down and Go Big

An 8" GDP Portal Gear Lift gives your Polaris RZR XP 1000 the room for huge 40" tires and the torque to turn them, thanks to 45%, 60%, or 70% gear reduction. With dual idler gears and precision-ground 9310 steel gears, these portals are built for strength, durability, and serious mud performance.

Portals place the gear reduction in the hub, after the rest of the drivetrain, helping reduce wear on axles, differential, transmission, and prop shafts while unlocking more of your machine’s potential.

Features:

  • 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. forward and rear offset
  • Increases width by 4 in. per side (8 in. total)
  • 1.5 in. diameter 4340 hardened steel drive shaft
  • Housings use advanced gaskets or O-rings
  • Universal hub fits all major bolt patterns
  • Gear reduction reduces stress on your drivetrain

Strong construction and sealing:

  • Reinforced housings are optimized for gear retention and oil flow
  • Advanced steel alloy backing plates are stronger than chromoly
  • Integrated rear hub backing plates help eliminate failure-prone aluminum hubs
  • Advanced gaskets and O-rings resist oil deterioration
  • Sealed input gear and double-lipped output seal
  • Double-angular contact output bearings help prevent premature wear
  • Roller idler and drive bearings maintain perfect gear meshing
