I could call Tader but...

OK... I have updated the front on my Smackdown... flat x-member, raised right rail, raised crossmember. I have Smackdown and S-7 spindles.

What length lower control arms do I need. I have a 19" rightside PPM...use an 18-ish left side?

Let me know...

I believe it calls for a 16 5/8" lower, with a 10 1/2" upper.

Just wondering how a 19" will work with the 16"+. MBR might be able to chime in...

Krooser, I've run 19 5/8 and 20" with the S7 on rf. I used a 17 5/8 lf

Thanks to all... I think I have a 17+ in stock.

Does your LF upper still mount to the inside of the uprights (whatever they're called), or did you update those to the curved style? Just thinking out loud...wondering how you'll keep positive camber in it with a longer lower.

Uprights are still stock early Smackdown. I don't have a lf upper yet...was figuring on using an 11"... not sure about it. I have 8 1/2" rf uppers.

Jet bring up a good point, if you have to mount inside, then your upper arm has to get longer. Rf is easier, just space out.
