Polaris RZR Pro S 8" Portal Gear Lift

8" Portal Gear Lift for the Polaris RZR Pro S

Add a full 8 inches of ground clearance to your Polaris RZR Pro S with a heavy-duty portal gear lift kit. This system raises the axle centerline dramatically above the factory position, delivering the clearance needed to run massive tires and dominate deep mud, rock gardens, and extreme terrain.

Maximum Ground Clearance
The 8-inch portal gear lift raises your RZR Pro S's axle centerline 8 inches above the factory position — double the clearance of a standard 4-inch portal. This puts the axle tubes, differential, and CV joints well above the obstacles that destroy stock-height machines, and opens the door to running the largest tire sizes available.

Gear-Driven Design with 45% Reduction
The portal housing uses a precision gear set with a 45% gear reduction ratio, providing massive low-end torque multiplication. This reduction compensates for the larger tire diameter and gives you the pulling power to crawl through the deepest mud holes and steepest climbs without straining the drivetrain.

Heavy-Duty Axle Shafts
Each portal assembly includes upgraded axle shafts designed to handle the extreme mechanical advantage of the 45% gear reduction. The shafts are machined from high-strength chromoly steel and heat-treated for maximum durability under the sustained loads that 8-inch portal lifts generate.

Direct-Bolt Installation
This 8-inch portal gear lift bolts directly to the factory knuckles and hubs of the Polaris RZR Pro S using the included mounting hardware. No welding, cutting, or drilling required — the entire installation uses hand tools and can be completed in a single session.
