Portal Gear Lift 4 Inch RZR XP 1000 15% Dual Idler

If you’re looking for increased clearance, stronger torque delivery, and drivetrain protection, the Portal Gear Lift 4 Inch RZR XP 1000 15% from High Lifter delivers the performance serious riders demand. Designed specifically for 2024–2026 Polaris RZR XP 1000 and XP 4 1000 models, this heavy-duty portal system adds a true 4 inches of lift while providing a balanced 15% gear reduction for improved low-end power without sacrificing trail capability.

This upgraded dual idler design spreads load across twice as many gear teeth inside the gearbox. By doubling the contact area, stress is reduced significantly, resulting in smoother torque transfer, improved durability, and less strain on belts, axles, differentials, and driveshaft components.

15% Dual Idler Performance Benefits

• 15% gear reduction – Ideal balance between torque multiplication and ride speed.
• Dual idler gear system – Increased tooth engagement for reduced internal stress.
• Improved engine braking – Extends brake life and enhances downhill control.
• Reduced drivetrain wear – Helps prevent premature belt and axle failure.

If you’re running larger tires but still want responsive trail riding performance, the 15% reduction ratio offers reliable power where you need it most.
