Matt, Tom, You guys ROCK!

Thank you both so much for taking the time to provide such detailed answers. It truly helps.

I'm going to chew on this info for a little bit and discuss with Mike (my mechanic) tomorrow.

Matt - with regard to Regional Chapters that is 100% within my plans once I get to WA at the end of the month.

 

Fwiw I went full pro comp front and rear on my v10 2003. No blocks all springs. added hellwig rear sway bar as well. Ran 35s on 18 inch wheels. Handled awesome. Rode like a tank. Will be doing v mod b on my 04 (just got it).

 

Duh, of course we do!
We are like awesome twins, but I'm the smart good looking one.

 

FWIW I used used X codes off an F550 and modded some used b codes out back. With this I got 2-2 1/4 in front and 2 inch in back, this was after a couple weeks of driving.

I have used airbag and install them very regularly, they provide an extremely rough ride if you are airing them up to provide a ride height much higher than the springs initially provide. I would only use them as a helper spring in case you tow.

25 3/8 and 25 3/4 are rear center of hub to bottom of wheel well trim

24 1/2 is front measurements respectively.

My plan is to eventually add 285 75 18 tires (35" but not a wide tire) of its tight I will add a hanger spacer or add a couple leaves under the front spring as needed, and out back change to a taller pu rear block under the spring.

I'm really happy with the mild lift I have, it's way better as in firmer than stock. No more bottoming out. If I didn't to often if I did it again I would consider one of those mini packs upfront with an add a leaf in the back.

But, my excursion was all over the place and wanted to rule out the sub pat stock springs without a doubt. While it helped mildly without towing (I haven't towed with the changed springs) it definitely feels more stable and planted all the time.

My wandering issues got thoroughly fixed via a new redhead steering box this week.

Right know, with stock 265 75 16 tires I'm as good as gold.

I wanted to thank everyone for the awesome information and feedback. Totally cool of you guys.

I just got off the phone with Junior at ATS. He's very knowledgeable and was extremely helpful. He's going to be sending me an estimate shortly so I can place my order to swap the leafs!
