Description

High Lifter Dual Idler Portal Gear Lift – 15% & 30% Gear Reduction

Upgrade your off-road performance with the High Lifter Dual Idler Portal Gear Lift, designed to deliver unmatched strength, torque, and reliability for serious riders. Each kit includes four precision-engineered portal boxes that redefine power transfer and durability. With your choice of 15% or 30% gear reduction, this innovative lift provides maximum torque to conquer mud, rocks, and rugged terrain with ease.

Unmatched Dual Idler Gear Design

High Lifter’s advanced dual idler design distributes load across twice as many gear teeth, cutting stress in half while ensuring smoother torque transfer. This means stronger acceleration, reduced belt wear, fewer broken axles, and longer-lasting driveline components. The improved gear reduction also enhances engine braking performance, helping you maintain better control and reduce brake wear on steep descents.

Forged Gear Boxes for Extreme Strength

Built from forged aluminum, these gear boxes offer unmatched toughness compared to cast or billet alternatives. Forging creates a dense, durable metal structure that resists impact and fatigue, giving you confidence to push your machine harder and farther. The robust construction ensures more worry-free miles in even the harshest off-road conditions.

Advanced Sealing and Venting System

High Lifter engineered these portals with dual oil seals on the spindle shaft and a triple-sealed input shaft, including a wiper seal for extra protection against water and debris. The optional venting system promotes cooler operation, reducing gasket wear and extending the life of internal components.

Premium Gasket and Backing Plate Design

Each portal features high-density Kevlar fiber gaskets that resist oil, coolant, and pressure without needing additional sealant. The 5/16-inch steel backing plates with bent flanges and welded gussets deliver maximum rigidity and alignment with factory hub specifications, ensuring superior strength and stability on every ride.

High-Performance Rotors and Gear Profile

Precision-ground stainless steel rotors provide consistent braking and heat dissipation, while slotted designs enhance cooling and performance. The CNC-machined alloy steel gears are heat-treated for superior strength and are lapped for quiet, smooth operation and easy installation. These details combine to create one of the most dependable and efficient portal gear lifts available today.

Tire and Wheel Compatibility

Fits tires up to 33 inches with portals and 35 inches with forward arms. Compatible with 14-inch or larger wheels (14-inch factory wheels require a 1-inch spacer). For optimal clearance, 14–15-inch wheels should not exceed 4.5 inches of backspacing, while 16-inch and larger wheels should not exceed 5 inches.

Experience industry-leading performance, strength, and reliability with the High Lifter Dual Idler 4” Portal Gear Lift—the ultimate upgrade for riders who demand more from their Polaris RZR. Designed for durability, precision, and unmatched power, it’s the perfect solution for tackling any trail with confidence.
