Leaf under suspension.

[folkenheath]

You could to the opposite of Jeep people and put a Jeep axle in your Chevy and do a spring under.

Personally I think spring unders are only good for lowered 2WD street trucks. Doesn't belong on a 4WD truck. Why not start with a flat spring at ride height that will flex both ways like a stocker. You aren't going to get that much uptravel with a solid front axle anyway unless you move the engine back or your springs are so arched to go under the truck and still give you lift that they are too stiff.

To go to that much trouble to modify the pumpkin and the axle and everything to put the springs under your axle and get less clearance and more arch seems stupid when that time could of been spent putting in a cheap coil spring conversion like the stock front dodge truck suspension.

Yah sounds like alot of work. Ill prolly just go with the ord alcan springs up front, my shackle flip in the rear and some bilstein 7100s all around with air bumps. Just was interested in the concept.

When I was talking to alcan over emails about my hopefully sooner than later tough truck build. When I was contemplating either soa or sua he said the soa would work just fine, didnt get technical but pretty much said spring under will just cost me more cause of the addional lift they gotta put in the spring. Other wise I was just looking at getting jeep axles to put under it.

Here's the truck from above. It wasn't a ton of modifications, he cut some of the pumpkin and made a custom spring perch. Worked out well...

Made a matching one for the other side so the overall height was the same...

This was pre engine crossmember and crossover steering but its all in...

That arch doesnt look crazy... What length springs are they? Prolly not stock length?

 

[Avery4jc]

No not stock length. I'll have to ask what application they were for.

My jeep goes pretty damn good through the track at prairie city. I was surprised. Jumps pretty well too, just ask mike lol. I have a ton of up travel and you can tell when I ram into stuff. I think with a good pair of shocks it would be awesome.

 

[TheBeast_88K5]

It jumps better than you think a YJ would...

so, just by coincidence I may be getting a project truck that is sitting on some big springs, like 8-12" lift springs, would these work to use with a SUA set up for the dunes? or would I be better off going to some stock-4" SOA springs (I have both on a scrap truck). I'm thinking the big springs will probably be too stiff. Just wondering what others think...

this is the truck I may end up with...
