i have two books that say when upgrading rear arms to make sure that the upper arm front busing should remain rubber. not hard like the poly ones. anyone have experience with this? i am looking at arm kits but they look like they all come with hard upper front bushings.

thats basically a 'street friendly' piece of advice. if you plan on launching hard with minimal tire break, switch to hard bushings. if you want streetablility that will kinda cushion the road, stay rubber.

I went UPR uppers and polyurethane spherical bushings and Lakewood Action/Treaction lowers

the sphericals go in the housing part of the upper arm right?

I once heard the same thing about the front bushings needing to stay rubber. I was under the impression that the reasoning for this is to eliminate a potential bind(with poly bushings) that could damage the torque boxes.

that's what i read also. i'll probably go with the Ford upper arms because i figure they know best. and sperical on the axle end.
