Now achieve the look of a G550 4x4 Squared with our Portal axle conversion kit. This 100% bolt on kit will lift your suspension 6 inches and add 40mm of offset to the wheels. This is the best way to lift your G-wagen reliably. No speedometer re calibration is needed.
In a portal axle, the axle shaft is above the wheel hub. At the ends of the axle is a more complex system of gears that translate motion downward to the wheel hub — an added step that allows the axle shaft to be higher than the center of the wheels. Essentially, the axle rotates on a higher plane than the wheels, which allows, among other things, for higher overall ground clearance.
All products installed and tested on vehicles in house. We do not sell any product we don't test personally. We are not an online re-seller much like other sites online selling G-Wagen parts. We have over 50 years of combined G-wagen service and performance knowledge. We fabricate and build all Eurowise products in house.

What you might want to know about portal axles: Front and rear axles are
rigid axles with portals, this means that the axle tube and the
differential housing are situated above the wheel center.
reduction guides the power to the wheels. Portals will give your
vehicle a unique ground clearance. The portal gear ratio reduces the
load on the complete drive train since the torque acts only on the
wheel. With our solution, the vehicle's suitability for everyday use
remains intact and the ABS system also works as usual, only the maximum
speed of the vehicle is limited to 160 km/h. “Bolt On Portals” are
portals that are installed on the existing axles. They are designed in
order to maintain the rotating direction of the axles. This is
accomplished by using 4 cogwheels in the portal. Another advantage of
using 4 cogwheels is that the load is distributed to the tooth flanks of
several cogwheels so that more power can be transmitted while the
increase in temperature is considerably lower. A portal gear ratio of
1,16-1 is equivalent to the reduction of the load on the axles. Of
course, the overall axle ratio changes corresponding to the factor 1,16,
which makes it possible to drive large wheels without having to adjust
the gear ratio of the differentials. The portals will give the vehicle a
“lift” of about 4 inches (10 cm). No further modifications have to be
made to the suspension in order to drive larger wheels and the entire
axle and steering geometry is maintained. This is the only way to really
achieve a proper ground clearance. The additional ground clearance
under the differential is 10 cm due to the portals plus the additional
ground clearance through the use of larger wheels; wheels that are 25 cm
larger than those you normally would drive. There is actually no need
to mention that wheels that are 25 cm larger would mean certain death
for most axles, let alone the expense for the expensive modifications
that are necessary to install such large wheels. The portal kit contains
the following parts: 4 portal boxes with pre-installed gear units, 2
outer front steering knuckles, 2 new HD front CV joints, 2 new HD rear
axle shafts, 2 rear brake callipers with integrated parking brake, 1 set
of front and rear axle clamps, 4 new ABS sensors, mounting bolts
Higher Ground Clearance
The obvious benefit inherent in a portal axle setup is more ground
clearance. The axle — an unbroken, horizontal shaft — is raised above
the mechanism that controls each wheel, so the lowest point in the
center of the vehicle is higher than normal. That’s the case with the
Mercedes-Benz 4×4. It affords a maximum of 17 inches of ground clearance
as opposed to the current “normal” Mercedes-Benz G-Class, which has a still above-average 9.5 inches.
Simply put, the portal axle setup allows for less work in the
differential and axle mechanism to translate to more torque at each
wheel. The axle half shafts can spin at a greater speed but generate
less immediate torque, meaning less work at the outset and more
productivity at the end of the machine. Differentials, then, can be
smaller, thus further increasing ground clearance, which, coupled
together, provides more overall capability off-road.
