Product Developed by IR4x4:
Due to the need for correcting the pinion on all lifted Land Rover vehicles, IR4x4 developed and created the the adjustable pinion angle adaptor, machined out of chromoly with a 1 amd half heim joint. The unit is completely bolt in. This provides for the fastest and easiest way to adjust your pinion angle.
Pinion angle is one of the more important measurements on a lifted vehicle. The wrong angle can lead to drive line vibration and premature failure of U-joints, drive shafts, pinion bearings and even transfer case output bearings.
