I think the lowest you could go with off the shelf stuff would be 4" (3" Springs and the hanger adds an inch)
If you made your own spring packs (combo of rears and front leafs is popular) you could do it though. Should be lots of builds on Pirate4x4 with pics.
Mine was 4" springs with the hanger and it was way to tall. It made the 36's look small.
Ya I was looking through all the sas threads and the trail gear 3" jacks it up high!
I was thinking of maybe removing a leaf or two and drill the shackles to a closer eye to eye position. But then I heard there may be problems with the high steer clearance.
This guy used the TG kit but used the stock shackles and got some leafs made up at a blacksmith (3 pack)!He is using 33'' tires on there.
I'm not looking for crazy flex , just something that is strong and that I can depend on since I'll be driving 12,000km with the truck this summer in remote places.
