Polaris RZR 4 Turbo S 4" Portal Gear Lift 15% Dual Idler Version

Polaris RZR 4 Turbo S 4" Portal Gear Lift 15% Dual Idler Version

This High Lifter 4'' Portal Gear Lift is designed for toughness and ready to take on any challenge. The gearing setup includes two idler gears in the portal box, distributing the load between twice as many teeth on the gears, reducing stress and allowing for more abuse. This kit is ideal for riders seeking enhanced torque and power.

Features and Benefits:

• Dual Idler Gear Design: The addition of a second idler gear in the gear box spreads the load over twice as many teeth, doubling the area and reducing stress by half, resulting in more reliable torque transfer, reduced belt and axle damage, improved engine braking, and enhanced performance.
• Forged Gear Boxes: The strongest boxes on the market, forged for toughness and durability, providing more worry-free miles than any other portal.
• Gear Box Venting: Optional venting kit available for cooling, reducing early deterioration of gaskets and seals.
• Gasket Material and Design: High density Kevlar fiber gaskets with no additional sealant needed, creep resistant, and oil and coolant resistant.
• Seals: Dual oil seals on the spindle shaft, preventing water intrusion and oil leaks, with a true triple seal on the input shaft for extra protection.
• Backing Plate: 5/16” steel plate with bent flanges for strength and durability, designed to factory off-set, and works with all control arms built to factory hub specifications.
• Rotors: Precision ground stainless steel with slotted design for heat dissipation and cooling, providing excellent brake performance.
• Gear Profile: Alloy steel heat treating process increases overall strength, with CNC precision ground machining for excellent fitment and increased durability.
• Tire Fitment: Allows for up to 33" tires with portal and 35" with forward arms (fitment guide is general and may vary based on modifications).
• Wheel Requirements: Compatible with 14" or larger wheels, with specific backspacing requirements based on wheel size.
