Im in the process of adding a RK LA upgrade and am a bit confused on the whole angle/arm length thing. Anyone out there help me out.

heres some pics of what I have now.

I would just eyeball it and let the alignment shop that you trust set the camber at the correct angle from their book. I don't know what it is supposed to be off the top of my head. PM lowrange2 he has a set of longarms and probably has the correct caster angle handy.

In fact, I have those exact long arms.

Where did you put the angle finder to find your 7* at? IMO, you should set the lower arms so that you have a good amount of thread engagment, then thread the top arm in untill you have your desired caster angle. A caster angle between 6*-9* is ideal. I've had the best luck right at 7*. Sorry for the vague answer. Feel free to ask more specific questions.

Btw, I love the new arms. Did you plate the unibody rails? I did. It made everything feel so much stiffer!

Also, how long ago did you purchase that bumper. I've been trying to get in touch with Mr. Logan Metal Fab but haven't had much luck. How much are they going for now? Gotta love ebay!

See I told you he had the info you needed.

Btw, The best place to check caster angle is on top of the upper ball joint for each side.

Thnx for your input, I had the angle finder on top of the diff. Ill remeasure it and see. I dont have any plating on the rails, but I do have a cage to help with the uni-flex a bit. I got the bumper about a month ago i guess. I had great customer service with them. They had a problem with thier powder coating guy, and they called me and were very easy to work with. I paid about $400.

Yeah, I'm not really sure how accurate of a reading you will get there. I may be great but I've never tried.

I plated my frame rails as I was installing the RK kit so it made all the kits measurements incorrect and I had to modify everything. What a headache!
