Default Rear Springs Part #

I'm having DEAVER Spring make me a custom set of rear springs ... They're going to be 1.5" Taller in the back but have the same spring rates as factory so it wont affect my towing capacity but will give me a 1.5" lift in the rear. I'll be ordering them first then use them in conjunction with a 3" lift in the front using cognito suspension bits...

You wont get a full 3" out of the front without CV joints vibrating at 70+ mph. Why not use Samco coils and Airlift bags in the rear. This will net you anywhere from 1" to 2" higher in the rear depending on air pressure. The air bags will help with towing and are cheap. I saw an auction end on ebay for a brand new airlift airbag kit for an H2 for $35

The Samco coils are now on sale for $350 and offer 2.5" more extended length over stock coils. This extended length will allow you to run taller shocks to go with your front setup.

3" lift in the front, the CV joint will vibrate ?!?!?! Damm !!!

I just want to level my ride out then... The reason why I dont want a lift is because it cause too many thing to be change out...

I just want to level the Rig out and run cognito suspension bits, green keys, and Fox shocks all around... Leveling the rig out will it cause anything to vibrate or out of whack ???

I think I know what you want...so here goes

-Cognito control arms, HD tie rods, Pitman/Idler support kit, OEM length sway bar end links, front extended shock brackets
-Samco rear coils
-Airlift air bags (install each bag with seperate valve stem for each side to control sway)
-OEM length Fox front shocks for 2500HD Chevy pickup. Dont use an H2 OEM length front shock with the Cognito extended length shock brackets unless you are prepared to modify the brackets and have these tools/skills!
-Use Fox rear shocks for Dodge Pickup trucks that are about 2-2.5" longer for the rear. These are perfect for an H2 with taller free-length coil springs!

If you go with taller coils (other than Samco) you will have coil bind before you fully compress rear shocks and make contact with OEM bump stops.
