Why We Make It 
We were tired of blowing our transmission whenever we made a minor mistake behind the wheel of our Polaris RZR XP 1000 . That’s why we designed and built a better, beefier GDP transmission case. Now instead of sitting at home for weeks praying to the warranty gods, we are back on the trail abusing our machine all we want. No matter how we drive, our GDP transmission case can take it. 

Beefed up in All the Right Places 
We’ve broken plenty of transmissions so we know where the stock case is too thin. Places like the snorkel gear tube and the axle output area were constantly chipping and fracturing to allow mud and debris in which ultimately destroys the entire transmission. 

We made our transmission stronger in all the right places but only added 1 lb of material over stock. Our snorkel tube and axle output has 68% more metal, plus additional support ribs and gussets. Those gussets and fins also help to keep your transmission cool. We went overboard on strength to ensure this is the longest lasting and best designed transmission you can get for you RZR XP 1000. 

Ride How You Want To 
Get your drivetrain in gear and ride how you want to with a SuperATV Transmission case. If you’re tired of feathering the gas, riding the brakes, and going around obstacles it’s time to upgrade to a GDP transmission. It’s time to ride with confidence.
