Default Caster Shims, degree question (leafs)

Hey guys I have a 4" spring lift on my 40.

I am swapping out all my front end hardware and installing new ubolts and skid plates on the front spring packs.

I need to get some new shims for the caster angle up front. I am degree clueless, any idea what to run? 2, 4, and 6 degrees are my choices from billet aluminum. Anyone know a source for steel shims?

Thanks in adavance!

Drew

My steel shims are from 4Crawler too. Any angle you want. Weld them on the perches front/rear. That way, you can grind them back off again later when you cut and turn your axle or perches.

Cast aluminum shims have a funny habit of snapping in half and getting spit out of the pack. I've personally had it happen on a CJ7.

And I think Rezarf also had that happen IIRC. +1 on 4Crawler. And if you guess wrong on the degree, he will take them back and send you the right ones.

Friends don't let friends use aluminum shims. They save that for enemies.

The other nice thing about the 4 crawler shims is that he will custom cut them to match the desired angle, width, length and pin location of your perches and spring packs. I sent him dimensions and got exactly what I wanted. He sent me some longer pins too. I've had them a few years and no problems. My manual steering 40 with 34" swampers doesn't vibrate or wander.

Martin what degree did you order. I gotta be honest, I read the article and though I understand it, I would prefer some more input before ordering.

6 degree shims seem like what I had before.
