High Lifter 30% Dual Idler 4 Inch Portal Gear Lift - Polaris RZR Trail, 900, General

• 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
  
• 30% gearing extends brake life by needing brakes less often due to greatly improved engine braking

Gear Box:

• 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:

• 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:

• Strongest backing plates on the market
  
• 5/16” 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:

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

Gear:

• 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

Optional Rotor Upgrade Kit:

• Requires 18" or larger wheels
  
• 18" wheels cannot exceed 4.5" backspacing
  
• 20" and larger wheels cannot exceed 5" backspacing
  
• Gives an additional 30% of leverage at the rotor
  
• Improves braking performance
  
• Gives more holding power at the wheel
  
• All components are designed for bolt-on replacement without modification
  
• (4) 13" precision ground stainless steel rotors
  
• (4) CNC precision machined caliper mounting brackets
  
• All mounting hardware and instructions included
