To lay frame on 22"s requires Airbags all the way around, and a 2,3,or 4 link in the rear. In order to get the front down you will need to modify the following:
Remove front fender wells
Notch the frame just in front of the engine crossmember to clear the Tie Rods when layed out.
Cut 1/2 inch off the exhaust just behind the engine crossmember.
Notch the frame where it comes in contact with the lower control arm when layed out.
You may also need to notch the firewall especially with 22's
You will need to Fabricate custom front shock mounts unless you are going with Synthetic Rubber Airbags I.E. Slam Specialties.
For the rear you would need a link set-up whether it be 2, 3, or 4 link.
You must tub the bed , and notch the frame to clear the axle coming up when layed out.
$2500 will barely cover the cost of the Air management system as well as the bags and all the hardware. Especially if you want bolt on stuff. It gets expensive real quick.
I built the green truck in my Avatar. it is a 95 Chevy c1500 on Bags laying frame. I built the truck to lay out on 20's. I built a custom 2-link with a trac bar for the rear. If you cant weld its probably not something you want to tackle. It is alot of work. Hope this helps.
