Find yourself a Ridepro stockest and save yourself the best part of $400.

Mine is great, their 40mm kit raised my disco 3" with the roof top tent on and now with the 235 85 rubber, it's not a monster truck but it has plenty of clearance.

Dont bother with a caster kit, mine wanders less than it did as standard with the raised suspention but thats probably replacing the original shocks that helped that.

OME is great but very pricey, Kings and Ridepro I think are about the same quality at a more reasonable price.
