View Full Version : Stock Control arms w/CAD not enough caster

I reciently installed a 4.5 inch lift and installed a control arm drop to improve caster and pinion angles while still using the stock control arms. However, I can only get about 2* of caster with shims and the front end wonders quite a bit at speed.

Has anyone had this problem and do I need adjustable or longer control arms to bring the caster angle to factory specs?

I would say adj uppers since DB's tend to move the wheels pretty far forward anyway.

Caster and pinion angle are a tight subject and will battle each other until death. You are not going to get optimal caster (5-7 degrees) easily with a lift on a solid axle without cutting and re-welding the knuckles. If you do, you will most likely be eating front driveshaft u-joints and/or yoke ears if you wheel anything mediocre.
