Slee 91-07 Land Cruiser Adjustable Rear Upper Control Arms

The rear upper control arms forms part of the rear 4 link suspension. When the rear suspension is lifted, the axle will rotate backwards thus forcing the differential pinion to point upwards. The result is that the pinion angle of the rear differential and the flange on the transfer case are not parallel anymore. This can introduce vibrations in the driveshaft. By making the upper rear control arms adjustable, one can rotate the pinion angle down and correct the angles, thus eliminate vibrations.

These arms are complete replacement arms with new polyurethane bushings. The joint allows adjustment of the arms on the truck.
