For even more strength, choose the dual idler configuration for the strongest portals available.\u003c\/p\u003e\u003cp\u003eRocks, trails, and mud are no match for a portal gear lift. A 30% gear reduction gives you extra torque for turning big tires in tough terrain, while a 15% gear reduction delivers punchy torque with more open-throttle fun on trails and tracks. Because the gear reduction is located in the hub, your axles, differential, drive shaft, and transmission work less and wear less.\u003c\/p\u003e\u003cp\u003eChoose from reinforced cast aluminum or USA-made, CNC-machined 6061 billet aluminum housings, supported by steel alloy backing plates for trail-proven strength. The dual idler gear setup spreads the load across twice the surface area for more reliable torque transfer, and the precision-ground 9310 steel gears are designed for strength and smooth operation.\u003c\/p\u003e\u003cp\u003eFeatures include advanced gaskets and O-rings, a sealed input gear, double-lipped output seal, double-angular contact output bearings, roller idler and drive bearings, and a 1.5 in. diameter 4340 hardened steel drive shaft.
