Default Custom steel shims?

Anyone know of a good source for some steel axle shims to fix caster? Every time I go to 4crawler.com, it seems he's either not accepting orders at all or massively delayed (currently, delayed until April). I've ordered from Rocky Road in the past, but that took about 6 weeks. Is there another option that won't take quite that long?

Thanks!

I'd prefer to stick with steel, especially since the amount of caster correction is so high. 6 degrees for an HFS 4" lift w/ extended shackles. Sounds like a lot, huh?

That does seem like a lot. I have a 4" lift and extended shackles as well and I measured/figured 4 degrees, which 4 crawler had in stock and I had in hand within a few days. Remember to get the extended spring pins too.

Sitting on flat concrete in my garage, it has between 2.5 and 3 degrees of negative caster. I'm aiming for about 3 degrees of positive caster. I've heard that 1 degree positive is stock, but that a little more than that can make it track nicer with bigger tires. Please someone correct me if those numbers sound way off.

Good call on the pins. I'll get those, too.

I already have 4 degree shims, but my numbers would appear to indicate that wouldn't be quite sufficient for ideal caster. Not true?

Depends on how bad it is and how accurate your measurement. Buy a cut and turned axle housing. Better solution to shims anyway. If anything you want a little on the + side with larger tires.

how large is the shackle?
