SUPERATV Polaris Sportsman XP 4" Portal Gear Lift

Polaris Sportsman XP 4" Portal Gear Lift 

Why We Make Them 
Take back your torque with Gen 2 Gear Driven Performance by SuperATV. We all know monster tires rob your much-desired horsepower. To keep that ultimate performance and gain an extra 4" of coveted lift, you want GDP from SuperATV. 

Why GDP? 
The GDP portal lift system spares no details as the most comprehensive kit on the market. SuperATV knows suspension and transferred over 10 years of suspension engineering into the GDP portal lifts. GDP starts by vertically relocating the axle centerline while retaining factory steering geometry - a must if you want to increase the life of your axles, differential, and drive train components. Pair that with a 1.4:1 gear reduction (approximately 30%), and you've got a performance driven machine!
