What's your caster?

Question aimed at the ones running 35" tires and 5" or 6"+ lift. But what caster are you running? And maybe what have you experimented with and what results did you have?

Pinion angle is more important than caster angle. You have to balance the two, enough pinion angle that there are no vibes, and enough caster for acceptable steering. Each XJ is different, so you have to determine what angles work for your XJ.

The only thing I have ever read that was believable regarding setting caster for large tires on an XJ said use minimum spec caster and maximum spec toe in for large tires. That makes sense to me considering all the other things I have read with respect to avoiding shimmy/death wobble. I think that minimum spec caster for an XJ is 5 degrees positive. The maximum toe in spec I have been able to find is 1/8". But I think it would make more sense to specify toe-in as an angle.

At 3.5" of lift, or now at 5.5" of lift, IDK what my caster angle is, or was. I have a reasonable pinion angle with no vibes, and the steering is acceptable. All I did was dial in more toe angle. Larger tires tire may need greater toe-in than smaller tires.

Thanks for the replies, I know about the pinion angle and everything. I'm not asking what I should be running, just researching what people are using and what is working best for them. All info is good.

The only way to get caster correct after lifting it is to cut and rotate the c's.

It's a pain but after doing it I have 8 degrees of caster with the correct front drive line angle. Its nice to be able to drive with one hand again on 35's

At 7" of lift, I have my pinion pointed straight at the drive shaft (each is at 10 degrees) and my caster is at 1.5 degrees.
Cutting the axle is too expensive ($600++) and adjustable ball joints only give about 2 degrees, so they wouldn't be helpful enough.
