A Better Transmission Case
We know a thing or two
about blowing a transmission—we ride just as hard as you guys do. You need a
transmission case that’s just as tough as your Ranger, so what did we do? We
built one, duh. Our stronger smarter GDP Transmission Case is built to keep
your Polaris Ranger running. Instead of sitting in your garage and praying to
the warranty gods, buy a better transmission case to replace your busted stock
tranny. With ours, you can ride however you want.

up in All the Right Places

We made this transmission stronger
than stock where it needs it most. The snorkel tube and axle output uses 68%
more material than stock and an enhanced design to maximize strength and heat
dissipation. We’ve added extra gussets and fins around the snorkel tube and
output shaft that keep your transmission cooler because a cool transmission
gives you cooler gears, and cooler gears give you a smoother ride. We pulled
out all the stops to make sure this replacement transmission case won’t get
replaced again.

Ride How You Want To
best part about a better transmission case is that you get to ride how you
want to. No more feathering the gas, riding the brakes, or taking the easy
path. Upgrade to a GDP Transmission Case, and take the outdoors head-on.
