Re: anyone running the calmini spring over?
If your considering a SPOA, and not wanting Wrangler springs (my current set up in the rear with SpiderTrax trac bar), I'd rec the Rancho springs with a Trac Bar....they rode well....but wrapped bad...why I pulled them...I would consider the Trac bar mandatory. I ruined 2 sets of springs, and I would not consider myself abusive with the gas. I've still got the Ranco's up front and it works well. They rode and flexed well in back, just didn't live long without a trac bar. I've also got the cross over steering....I'd rec that too. Also, don't forget your driveshafts...my rear needed replacement quickly due to major vibration.....and the front removed itself from my truck while being flat towed....oops. So, that adds considerably to the cost of a SPOA. If you don't want to get any welding done, I'd consider the Wranglers Spring under....I think some one had that set on the board, and looked like if worked well.
Hope this helps,
