The Portals are developed to maintain the rotational direction of the original axle which is achieved by using 4 gears inside the drop box.

Another advantage of 4 gears is the optimal distribution of torque on more gears.

Due to this fact a higher torque can be transmitted inside the drop box and temperature development is improved.

The reduction/gear ratio of our "bolt-on portals" 1,6:1 is equivalent with a 60% load reduction of the axle and drive-line. Or a 60% improvement of axle strength.

As the whole drive ratio is altered by the factor of 1,6, it´s now possible to use larger tyres without changing the differential ratio.

Our bolt-on portals increse vehicle hight by 5" (125mm) or 4" (100mm) for our standard drop box with a lesser gear reduction.

This hight increase allows you to mount larger tyres without changing your suspension or even cutting your body work.
Axle and steering geometry stays untouched.
The increase of height by the portals gives you a minimum ground clearance improvement of the same amount.

Available in two different version.
For off-road use with a ratio of 1.6 to 1 and for the off-road trip, a ratio of 1.16 to 1s.

4-piston calipers and ventilated disc brakes are included.
These new portals are made ​​of high strength aluminum to keep unsprung weight low.
The portals have a lift of 4 " to 5" ( 100mm - 125mm).
The maximum tire size, we recommend is 35"

Front and rear axles are solid axles with portals, meaning the axle housings and the differentials´ centre are located above the wheel´s centre. The gearing with its reduction, inside the portal housing, transfers the power to the wheel.
Portals offer the most unique ground clearance as the axle and differential housing are lifted and not just the frame or chassis.
Due to the gearing ration inside the portal drop box, the stress on the whole driveline is significantly reduced as the full torque is only occuring at the wheel and subsequently reduced inside the portals.

Especially for Rover and Jeep as well as adaptable to almost all other axes such as Mercedes or Toyota
Also available as a complete axle with eg Ford 9 ", Dana 44 or GM midsection.
different axle ratios of 4.0 to 1 to 8.5 to 1 possible.
