Gen 3 Portals Are Geared for All
Picture yourself riding 8 inches higher with increased power on your Polaris RZR Trail S 900. With a GDP Portal Gear Lift, this dream becomes reality. These portals provide the clearance and torque needed to conquer any terrain, with options to choose from cast or billet aluminum housings and a 45% or 60% gear reduction. Don't wait any longer - GDP is ready to elevate your ride.
GDP - Trusted Portals
While you may not be sure if GDP is the right choice for you, the thousands of riders already utilizing these portals every week would likely convince you. More riders trust GDP portals than any other system, providing unmatched experience in terms of reliability, quality, and performance.
Optimal for Mud Terrain
Spotting RZRs in the mud has become a common occurrence, thanks to its prowess in such conditions. Equipped with 8" portals and a 45% or 60% gear reduction, the RZR becomes the ultimate mud UTV. Accommodating larger tires and packing substantial torque, it can navigate through any mud obstacle.
Drivetrain Protection with Gear Reduction
Placing the gear reduction directly in the hub offers benefits, such as prolonging the lifespan of drivetrain components. GDP's system reduces stress on axles, differentials, prop shafts, and transmissions, even when fitted with oversized tires.

Premium Gear Material
GDP utilizes precision-ground 9310 alloy steel for top-of-the-line gears, ensuring seamless operation and minimal noise even at high speeds. Expect luxury-grade performance from GDP gears.
Robust Housing Design
In contrast to the belief that strength is achieved through brute force, GDP employs precise design methodologies refined over years of experience to produce sturdy portal boxes. Whether opting for cast or USA-made billet aluminum housings, customers can expect high-quality, precision hardware capable of withstanding rugged terrain.
Durable Backing Plates
Constructed using an advanced steel alloy stronger than chromoly pound-for-pound, GDP's backing plates are 5/16 inches thick and feature hand-welded gussets and pivot blocks. Strengthening the backing plates ensures prolonged durability, crucial for sustained off-road adventures.
Enhanced Gaskets and Seals
Both cast and billet aluminum housings incorporate:
Durable Bearings
GDP's system includes high-quality bearings essential for the portal's functionality. Equipped with double-angular contact bearings on the output shaft, these bearings can withstand impact, emphasizing the system's durability.
Universal Hubs and Slotted Rotors
Featuring precision-ground stainless steel slotted rotors designed to dissipate heat efficiently, ensuring optimal braking performance. The rotors support various bolt patterns and lugs, complemented by tapered output shafts for a secure lock that prevents wobbling or wear over time.
Frame Stiffener Requirement
As these 8" portals provide substantial lift and power, a frame stiffener is necessary to prevent chassis bending in your RZR. Trust GDP's experience, and consider adding a frame stiffener for added support.
