Proformance Live Axle Portal Reduction Hub
Reduction Drive Hub with CTIS (Central Tyre Inflation System)
For competitors that prefer IFS up front and a Live Axle at the Rear, Proformance provide a Reduction Portal Hub that bolts to your Live Axle Case or tubes. Customers simply weld their diff casing to our 4140 Chrome Moly "Weld On Flange".
Tractors, Mining Vehicles and Military Off Road vehicles have been using Portal Drives for more than 50 years to achieve more ground clearance, 100% more Torque at the wheel and 50% less load on the Diff Gears and Axles
Using the same internal components as our ULTRA4 IFS and IRS Portal hubs Our Live Axle Portal Geared Hubs provide a stronger drivetrain for ULTRA 4 racing, Rock Bouncing and Off Road Racing.
The 2:1 Gear Reduction in the Hub doubles the torque applied to the wheel whilst halving the load applied to your axles, diff gears and tailshaft.
As with all our Portal Hubs, the Bolt On Live Axle version comes complete with CTIS (Central Tyre Inflation) to allow you to deflate and inflate your tyres as you drive - perfect for for ULTRA 4 and King of the Hammer Race Vehicles.
