Sam something I did when I built my first Nissan when I could not afford uppers was Fabtech sold me balljoint plates and the bushing peices and I got my own tubing and welded a set of arms together for under $100 I dont know if they sell peices anymore but it saved me some cash at the time.. This was 7 years ago.

thanks for the tips - but i lucked out.
I have a guy selling me Dick Cepek upper arms for $100. These things are tubular, and they have a bend in em which he says provide 2-3" lift.
This works out right, cause i am just finishing up a rear leaf spring swap (hombrew: mazdas+toyotas) and that setup will be lifting the rear ~ 2"

Re: Extending stock toy A arms

Dylan,

Thanks for your formula, I have a few questions regarding it.

First off what are the units of measure for D, Lb, and La.
Also, I don't understand 11.2E6. Does that mean 11200000.

Couple other things,
Where can I find the "Dave's Spring Calculator" on the web. (or maybe you could e-mail it too me if its not too big)

Also, I checked out swayaway.com and couldn't find a tech tips section. I found a "suspension worksheet" section that applies spring rate formulas to coil over suspension but I wasn't sure how to relate that to torsional suspension.

Thanks again for your help it is much appreciated.

Jon:
The units for D,La,Lb are inches. Yes 11.2E6 is 11200000

I will try E-mailing that program to you if I can find the disc

On the suspension worksheet page just use “step #1 wheel rate” then play with the dimensions of your bar and arm to match that rate

Keep us up to date on how your projects coming along……Dylan
