Take the reins off your ride with SuperATV’s 8″ GDP Portal Gear Lift. With 8 inches of extra ground clearance and a torque-boosting 45% or 60% gear reduction, you can do what you think about doing but stop out of fear, and go places nobody else can.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGDP the Most Trusted Name in Portals\u003c\/strong\u003e\u003cbr\u003eGoing big isn’t risky. You’re following in the footsteps of thousands of riders that have chosen GDP before you. More riders roll on GDP portals than any other portal system. They’re out on the trail and parks every day, and with all that ride time, you can bet they’re the most trail-proven portals on the planet.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect for Mud\u003c\/strong\u003e\u003cbr\u003eA big lift plus a 45% gear reduction equals one mud-munchin’ monster.

Because it comes after your drivetrain, it reduces stress on your axles, differential, prop shaft, and transmission. So even if you’re riding hard, you’re doing less damage than stock.

Micro Polishing is a process that gently smooths out any imperfections in the surface of the metal during a two-stage, non-abrasive, burnishing process that produces a chrome-like finish. The result is unbelievably smooth gears that have almost zero friction or resistance. This means better oil retention and a longer lifetime than other gears. They will stay cool and quiet, while giving you a little more power to the ground.  \n\n\u003cstrong\u003eBillet Housings\u003c\/strong\u003e\u003cbr \/\u003eChoose billet or cast aluminum housings to finish your portals.
