Since I m going for a SAS too (I got Heather's and Nate's hybrid front axle ÂÂ

) , I ll tell you my opinion.The sas with coil set up will be more expensive than a SAS with leafs.Of course you all know that.I m almost ready to start the SAS project,just waiting for the last parts to be delivered to me.I believe that if someone wants to make a good truck with SAS ,he should expect to invest ("spend" for some others...) not less than 3000-3500 $,using both new and used parts.Coils or leafs.
Personally , I m going for a SAS (SPOA) using
-Heather's front hybrid axle
-OTT Kicker 3
- YJ leafs new
-Rancho's or Skyjacker's  shocks
-ARB front
-Mounting parts and other parts/kits from
*SpiderTrax ,TT,Calmini,Quadratec
- Custom driveshafts
I m expecting a total cost at aprox.5000-6000$,using new parts.(including custom import duties to Greece)
And I call it a cheap mod.I would like to get Calmini 's SAS kit ,but I couldn't wait any longer.
If I was going for Dana44's,coilovers,strengthening the frame,plus solution for slip yokes,e.t.c  I would be close to 7500$-8500 or more I believe.
There's no way I believe for someone to0 built a good SAS Sidekick with 2500 or less.
