They give you the ground clearance you need to fit up to 30″ tires, and with your choice of a 45%, 60%, or massive 70% gear reduction, you’ll have wicked torque that’ll rip through anything. Or get the most extreme portal lift with dual idler gears. If you want to turn your Ranger into the ultimate party wagon, get an 8″ GDP Portal Gear Lift.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is a Dual Idler  \u003c\/strong\u003e\u003cbr\u003ePerfection takes time. After years of research and development, we’ve made our dual idler gear portals unlike any other. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don’t do a thing if they’re not mated perfectly, though. Precision CNC grinding ensures ours do. Our gears are made from the industry’s toughest 9310 steel alloy. Didn’t think dual idlers mattered  With GDP’s quality and experience, they finally do.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e45%, 60%, and 70% Gear Reductions Dominate Mud\u003c\/strong\u003e\u003cbr\u003eGetting wild in the mud is all about going as big as you can. With 8″ portals and your choice of 45, 60, or 70% gear reduction, you can go bigger than you thought possible. You have the ground clearance to keep from getting swamped and the gear reduction to turn monster mud grips through the bounty holes that swallow other riders whole.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA Gear Reduction That Protects Your Drivetrain\u003c\/strong\u003e\u003cbr\u003ePortal gear lifts reduce the stress on your axles, differentials, prop shafts, and transmission.

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.
