If you’re running 40 inch tires or larger, this 6 Inch Portal Gear Lift 60% Dual Idler for Polaris Sportsman restores lost torque, improves engine braking, reduces belt wear, and helps prevent broken axles, differentials, driveshafts, and transmission damage.

60% Gear Reduction with Dual Idler Technology

High Lifter enhanced traditional portal box design by adding a second idler gear inside the gearbox. This dual idler portal system spreads the load across twice as many gear teeth, doubling surface contact and reducing stress by half. The result is smoother torque transfer, improved reliability, and longer gear life under extreme conditions.

The aggressive 60% gearing significantly increases engine braking performance, reducing brake usage and extending brake life while delivering maximum low-end torque for deep mud and technical terrain.

Forged Aluminum Portal Gear Boxes – Strongest on the Market

Unlike competitors that use cast or billet housings, High Lifter utilizes forged aluminum portal gear boxes. Forging produces a stronger and tougher housing structure, making these some of the most durable ATV portal boxes available for the Polaris Sportsman 850 and XP 1000.

These heavy-duty portal housings are built to withstand extreme torque loads, mud riding abuse, and oversized tire setups without compromise.

Advanced Sealing & Gasket Protection

• High-density Kevlar fiber gaskets – oil and coolant resistant
• No additional sealant required
• Dual oil seals on the spindle shaft for 100% more sealing area
• True triple-sealed input shaft including protective wiper seal

This multi-layer sealing system prevents water intrusion and oil leaks, making it ideal for deep mud, water crossings, and harsh off-road environments.

Optional Gear Box Venting

The integrated vent plug allows installation of an optional portal gear box vent kit to reduce internal pressure buildup, improve cooling, and extend gasket and seal life.

Heavy-Duty Backing Plates & High-Performance Braking

• Massive 5/16″ steel backing plates with bent flanges
• Welded gusset brackets for superior structural integrity
• Factory offset design
• Compatible with control arms built to factory hub specifications

The included 13 inch precision ground stainless steel rotors dramatically enhance brake performance. The slotted design improves heat dissipation and cooling, while access holes simplify service and maintenance.

Precision Machined Heat-Treated Gears

Heat-treated alloy steel gears are CNC precision ground to ensure proper mesh and strength. Controlled gear lapping improves installation ease and provides quieter operation compared to standard portal systems.
