Outer Limits 4x4 Board

what caster would be best for a trail only rig,I got to rotate the nuckles and this is were there at now

is that positive 3 or 4 degrees? that should be ok for offroad and onroad, i think cruiser and lux castor from the factory is positive 3. Are you linking the front or sticking with leaves? if linking make the upper/s adjustable.

Yeah linking the front now,the reason is for pinion clearance to bell housing(rolled the diff down),I want to stick with a high pinion
I`m not quite sure on pos and neg with caster but I`m sure thats neg,I`m sure it`s 2-5 pos is good for onroad

if you draw an imaginary line through the centre point of both swivel bearings this is the castor angle... if its pointing towards the front from zero its positive, back is negative, from the looks of your pic its positive 3-4 degrees.

We run the buggies @9 degrees

did you eye ball your castor angles sam? because they're not 9* and they're not the same either.
