Thank you

Thanks. No more pics right now. I'm taking them and posting them as I go. Before I started this project of lowering the truck, I did lots of research looking for pics and information on the internet and there is hardly any. That's why I started this thread, for anyone with questions or someone who wants to do it too.
No, the factory shackles and springs are used. Basically, to lower the front of the truck you have several options depending on how low you want to go (Drop axle with stock springs, stock axle with one leaf spring and an air ride set-up or a drop axle with one spring and an air ride kit, which is what I did). You can go even lower, but more mods are needed to the engine and chassis. My axle is about 1/2" from my oil pan with the air dumped, but I have a Cat C-15. If I had a Cummins or a Cat C-12 or C-13 there would be much more room to lower it if I wanted to modify the chassis.
If you guys have any questions, don't hesitate to ask. We are here to learn.

When you slicked the top, did you pull the lights and weld the holes shut?
Petes have a fiberglass lid so I assume he was able to putty them shut but I'll let him answer. lol

The roof is aluminum. I just pulled the headliner and capped all the holes with aluminum plate and cold weld (JB Weld).

The company I purchased the air ride kit from told me to remove all the alignment shims and spacers. The tires are 255 70R 22.5's.
Sorry, I stand corrected. Maybe just the ultracabs are fiberglass. I know every untracab I've been into is fiberglass.

I keep thinking about it, it has leafs and on 22.5 wheels just never good with how it would be capable. I like how you have it on air, so when I got to dump site could raise it up. I am defintely going to follow your thread and see where it goes and keep brainstorming for myself

Yup, I got the air ride and the visor from 12 ga. Great workmanship and great service.

do you have any pics of how you mount the front of your rear fenders? thanks

I have not mounted them yet, they are just sitting on the tires. The truck has Flex Air suspension so I'm still thinking of a few different ways I can make a front mount that looks nice. I don't want to get something that just bolts on like a Hogebuilt stainless fender bracket. I will probably make something and when I get to that point I will post pics of it.
