Drop boxes for 2" lift
Ok So i have a 2" lift installed and although caster is juts ok, i was wondering if anyone is using drop boxes, like zordoes, to give them more caster on a 2' lift which in turn gives more flex out of the front.
Also, for all those who are doing a small lift, the front stock swaybar links can be utilised by making up a spacer to drop the link back down, I used some rod i had at home, machined up about 20mm long and hay presto, works a charm. You need to compress the bushes to get the nut on with but works just fine.

Not castor, you get more flex by lowering the pivot point of the front arms, thus allowing more flex. Well at least that is the theory.

Hi Mate,
you will find that running a 2 inch lift you will be no where near the limitations of the pivot point and your limitation will be the sway bar and the length of the front shocks.
Fitting drop boxes is required primarily for Caster Correction and it would be argued by most that NO Caster correction is required on a 2 inch lift. Fitting Drop Boxes will cause an over correction and massive oversteer and really vague response i reckon.
At the end of the day mate there is no "Quick Fix" Your limitations are your 2 inch lift. Full Stop. All good for most and will get the job done but when chasing the next level it becomes "All In"
Hope that makes sense?
Cheers MR

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.

Thanks mate
The front shocks are matched to give maximum front travel, Extended Length 21.310 in. Collapsed Length 12.550 in. so should be just nice, the front sway bars are currently mounted at 5 degrees down from horizontal and give an extra 10cm of travel VS horizontal mounting.
I did experiment on the weekend, and found if i drop the pivot down 30mm, the over all travel increased 180mm with sway bars in and so forth.

hmmm? but based on the length of your shock you have a total available travel on the shock of 223mm only so to have an increase of 180mm are you saying that you only have 43mm of travel now?
21.31in (541mm) Extended length
12.55in (318mm) compressed length
8.76in (223mm) Total Available Travel

I understand that but you did say that more castor and therefor more flex.
On a patrol the big limiting factor is the distance between the radius arm mounts on the diff. On a patrol it is 230mm between mounts. An 80 series flexes better because they are 180mm, apart and a landrover is even better still and 150mm (from memory) The closer they are together the more the bushes are allowed to move. from this the roll resistance is less and handling is comprimised and that why a superflex arm only has 1 superflex arm not 2.
if you want flex from a 2 inch lift you need big shocks. if you want to go really big you need to sit down and engineer a solution to get everything right ie anti-sqat and anti dive geometries, instant centre etc. and if you are going that far I would just double triangulate the rear and a 3 link + panhard front

Not castor direct sorry.
The shocks i have are 2.75" extra over stock, when i measured my stock shocks, they only have 145mm of travel. GU8 that is. The measurement i am talking about extra travel is based on taking out the stock shocks and seeing what i can get away with in terms of travel and the stock mounting points and sway bars. Sorry should clarify the travel was split left right, so 40mm up on one side 40mm down on the other, ie crossed axle, i don't know how to explain it all but i know it works. LOL.
