Caster plates are used for correcting the caster on the Nissan patrol.

5-degree Plates should only be used on 4-5 inch lifts, if they are fitted on 4 inches or lower lifts the vehicle may experience 'head shake".

7-degree Plates should only be used on 6-7 inch lifts, if they are fitted on 5 inches or lower lifts the vehicle may experience 'head shake".

For smaller lifts consider caster bushes or drop boxes.

Caster plates are a bolt in item but a 90-degree drill is needed to fit them or they can be welded onto the original diff plates.
