Pionion angle ?

My rig needed new springs so I bought a set of 4.5" RE. They are a little taller than the 4" Terflex I have on now. They measure about 1/4" taller for the rear & 3/4" taller up front (from what my Tera's measured when I first got them). So I'm going to extend my lower control arms out about 1/2"-3/4" from where they are currently at to match RE fixed arm length for the 4.5" kit. My question is how much do you think this will affect my pinion angle? Noticeably to where I'll have to readjust it or will I be able to get away with not having to adjust the uppers? TY.

Go Anywhere.

The best way to tell is to measure with an angle finder. They're at Lowe's, Home Depot, Sear's, etc. for about $10.

Remember, lowers set wheelbase, uppers set pinion angle...
