Take Your Ridge to the Next Level with GDP PortalsTurn your Kawasaki Ridge into a true powerhouse machine with SuperATV’s 4" GDP Portal Gear Lift. You get a lift and gear reduction all in one package, with a choice of 15% or 30% gear reduction and cast or billet housing. It can also help you run up to 31" tires.
Tackle Any TerrainA 15% gear reduction is a good choice for faster speeds and solid torque. If you’re running larger tires and hitting rough trails, the 30% gear reduction is the better option.
Protect Your Kawasaki Ridge’s DrivetrainGDP Portals put the gear reduction in the wheel hub instead of the transmission, helping reduce strain on your axles, prop shaft, differential, and transmission so you can get ultimate power with less worry about damage.

If you need help figuring out which gear reduction is right for you, check out the portal gear reduction calculator. Max tire sizes are measured at full compression and full turn. The listed tire sizes are the largest we fit without rubbing; with minor trimming or a small amount of rub, larger tire sizes can be used.
