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 "- 5" (100mm - 125mm).
The maximum tire size, we recommend is 35"

Especially for Rover and Jeep as well as adaptable to almost all other axles 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.
Only for competition vehicles.

The main reason for offering this product is to be able to use car parks and underground garages. With the standard height of over 200cm is it not possible.
With the lowering the Defender is approx. 195cm high and you can use several parking garages and underground parking... More

Also the Defender 90 has a high additional load with 600kg. Therefore the rear springs are strongly designed, which is a benefit to the traveling comfort and wheel travel.

Its already outstanding cross-country mobility is once again clearly extended.

The suspension kit is exact aligned to the specifications of the Defender.
Better and softer response of the rear axle.
The Defender from 1998 onwards is quite hard on the rear axle when its empty due to the higher axle load.
The vehicle height remains the same.
The improvement of the driving comfort with this coil spring set is amazing. More

This spring set is designed exclusively for an optimal wheel travel. It contains a lifting of 30mm, in order to make more suspension strut movement available and improve the angle of slope. The springs are progressive and calibrated with a small rate. By this soft parameter the Defender adapts perfectly to the underground. More

With these coil springs you are able to lift your vehicle about 50 mm.
This Kit has the same construction characteristics and outstanding driving quality as our standard suspension kit. Besides the optical effect it improves the angle of slope, the ground clearance and enables to fit larger wheels and tires.

When mounting a winch, especially with reinforced bumpers, the Defender Series tends to bottoming out at high gear load. We recommend in this case reinforced front suspension springs, if the standard springs remain installed. If you fit a suspension kit, it can be delivered with reinforced front axle springs More

The manufacturer has developed an inner spring which is coiled in opposite direction and is little different from the standard spring when empty. At high vehicle load capacity acts a much higher spring rate, thus the drive ability remains proper up to a total weight of 3,500 kg. This spring is suitable especially for use with heavy trailers or caravans. More

The HANDLING KIT was especially developed by BILSTEIN for the use on the Defender and it is field tested.

An optimal adjustment of the shock absorption on the vehicle was achieved. The mechanical loadability is increased to prevent break down.

The result is a shock absorber with degressive rebound stage and tight aligned compression stage. This combination changes the ride of the Defender fundamentally. More
