Drop boxes or caster bushes
I have found a couple local suspension places able and willing to do me a 4'' lift
one guy is telling me around 2000 to use caster bushes with his set up and the other high 2s to 3 to use drop boxes they both basically wrote each other off and tried to push there method.not helpful at all when iam unexperienced in this field. Throw you honest opinions at me please as thats why im here to listen to those speaking from experience. Cheers

I have castor bushes but am looking at drop boxes as I think they make more sense.. its one thing to have the caster correction done but where it bolts into the chassis is on a greater angle and must wear the bushes there so much quicker??!!

Drop Boxes for sure. the Nissan Rubber radius arm bushes are great and should be kept at all costs. the caster correction bushes are nowhere near as good.
You can buy Drop Boxes off ebay for $280 and they are a straight bolt in. there should be no more than $150 difference between bushes v drop boxes. ask the cheaper guy for a price if you provide the boxes and i will get you a link to what i use in BOTH Cars.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

Caster bushes are a shocking thing really. A cheap remedy to correct your caster angle. The bush is the thinnest where you need it most. They change the centreline angle not ideal from the arm pivot to your diff. The new angle that the suspension has to travel up when hitting a bump isn't ideal and the rear bush takes alot of this shock.
Boxes help keep your arms at the correct angle and you keep your oem bushes at the diff for a more natural movement.

I agree with all that drop boxes are the way to go but from memory they are not legal. In QLD anyway. Something to think about when dealing with insurance if the event ever come about.

I run a 4 inch lift kit and castor correction bushes, I have no problems. I would love to be running drop boxes but police here are onto them.

The idea of the drop boxes is to drop the rear mount of the radius arm down to cope with the lift and still retain basically a Level radius arm so on compression it is already at the correct position of its arc of movement. With caster correction bushes the radius arms are pointing down still and on compression the diff actually has to move Forward in the arc as it travels up. This is terrible for bushes, bearings and pretty well everything else too, causes over steer a d can be terrible.
So your options are to retain the functioning factory Radius Arms with genuine rubber bushes, drop the rear mount using drop boxes and happy days. The Only Down side is that the drop boxes hang down and some might suggest that they get hung up on stuff? I am here to tell you I play pretty hard and can't think of a single time that I have been hung up on my drop boxes.
So the other option is manufactured drop arms. Very nice hit of kit indeed. Effectively they are designed to achieve that flat radius arm from the factory mount by increasing the drop of the front half of the arm. Nice but Very expensive. If you have the cash then happy days.
But for what it is worth mate Caster Plates are Junk. There is simply No Comparison between drop Boxes and Caster plates. The flex sideway and are rubbish.
There is nothing wrong with drop boxes. It depends who is selling to you and how much they think they can get you to spend
IMO
