High Lifter 45% Dual Idler 6 Inch Portal Gear Lift - Polaris RZR RS1

Product Details

Why does gear reduction matter?

If you plan to run bigger tires to negotiate rocky terrain or dive into a honey hole, you need a portal gear lift. The larger the tire, the harder your engine has to work to turn it while trying to maintain your speed. Polaris RS1 portal gear lifts allow you to increase torque at a lower RPM, reducing effort and stress on your engine. This provides greater gains on power and acceleration compared to installing a transmission gear reduction kit.

Dual idler gear lift, why is this important?

A second idler gear ultimately increases the number of teeth in the gear box which doubles the area the load is spread across. The result is greater power with the stress reduced by half for more reliable torque transfer. When you have less stress you provide longer performance life making the dual idler feature one of the best features available.

Significant return on investment

This Polaris RS1 portal lift adds 6-inches of ground clearance along with a massive boost of power when hammering down on the throttle. Since the lift for the Polaris RS1 lifts EVERYTHING, your stock (or aftermarket) tuned settings stay the same. High Lifter portals provide several benefits, now you have a rig perfect for rocks, mud or whatever you plan to conquer.Shared Shipping Program: You pay $40.00 shipping/handling and Side By Side Stuff will pay the rest.

  • 2018-22 Polaris RZR RS1
  • The dual idler gears spread the load over twice as many teeth on the gear sets, which doubles the area and reduces stress by half
  • More reliable torque transfer
  • 45% gearing extends brake life by needing brakes less often due to greatly improved engine braking

Gear Box Features:

  • Strongest boxes on the market because forging produces a tougher piece of metal
  • Forging is stronger than both cast and billet aluminum
  • Extremely robust and give you more worry-free miles
  • Offers a plug for venting with an optional easy to install kit that will be available soon
  • Vent kits allow an advantage of cooling which reduces early deterioration of the gaskets and seals

Gasket and Seal Features:

  • High density Kevlar fiber gaskets plus no additional sealant is needed
  • Creep resistant plus oil and coolant resistant
  • Two oil seals on the spindle shaft for 100% more sealing area
  • Dual seals prevent water intrusion and oil leaks
  • True triple seal on the input shaft which includes a wiper seal that provides a significant extra layer of protection

Backing Plate Features:

  • Strongest backing plates on the market
  • 5/16 inch steel plate with bent flanges for strength and durability
  • Welded gusset brackets and designed to factory off-set
  • Works with most control arms that are built to factory hub specifications

Rotor Features:

  • 13 inch rotor
  • Precision ground stainless steel rotors
  • Access holes for ease of assembly and disassembly
  • Slotted rotor allows for heat dissipation and cooling

Gear Features:

  • Alloy steel heat treating process increases overall internal and external strength
  • CNC precision ground machining ensures excellent fitment and increased strength
  • Controlled gear lapping for ease of installation and a quieter performance
