Outer Limits 4x4 Board

Finished the rear 5 link on the lux now starting the front sas.

What caster angle do you guys recomend for a front solid axle?
Any help or advise would be helpful.

The front sas is a coil front end from a bundy.
Not using bundy radius arms but 80 series arms.(to help with
castor and bonus being I can use caster plates or off set bushes if required)

Its normally 1- 2 degress (positive?).. anyway with the top of the housing leaning towards the rear of the car..

WHy not go a flip arm while u are at it?? more ground clearance then too

Castor is one of the most important things for a road rig, the higher the castor the better the rig will self centre and not wander accross the road at speed, also the less likely it is to shimmy.
According to specs, 80's can run up to 4 degrees caster.
I just set up a Bundy front end tonight with 5 degrees in a Paj.

Thanks guys
I'll aim for around 4 degrees.
Thought about flip arms but it gets a bit tight around the coil mounts
on the diff.
Would have to bring the arms further inboard and I don't really want that.

Yep 5 degrees in my Paj (Lux housing).......................

If running Toyota front radius arms you need to be carfull with big lifts and getting the caster correct as the track rod can interfere with the radius arms. I recently built a custom housing for a 100 series and gave it 3 deg with a 4" lift and there was no way the trackrod would fit. Had to rework the radius arm mounts on the diff to raise the centerline of the axle housing from the radius arm to enable the trackrod to fit. More caster is good but it is a comprimise good high speed stability and the steering getting too heavy caused by too much positive caster.
