[4.0B2]

and leafs set up right, will ride just fine, and flex just fine... you just gotta use the right leafs.

They will flex fine they will not give amazing flex like coils and coil overs do.

I would argue that the right leafs and the right setup will flex as much as needed if you're not doing some crazy buggy build.

I helped do a leaf spring build on a YJ a few years ago, it got a surprising amount of flex (took a little experimenting with spring packs to get it right, but it comes with the territory). We ended up doing a 3/4 elliptical in the rear while we were at it. It actually flexed better than my choptop that is running coils up front and leafs out the back.

That said.... for the OP, I would lean towards using coils or coilover/air shocks simply because the axle is most likely set up for coils and if you decided to go with something different, why convert the axle to leaf springs....

Like you said they don't flex enough for a buggy. Hence what I am saying coils and coilovers are better. Leafs can flex well, but they cannot flex as well as a correctly setup coil/coilover. I have a great flexing set of rear leafs on my XJ has ton's of up and down travel, but it is nothing compared to the up and down travel the front has with its correctly set up 4 link.

To go to coil overs would take just as much fab work as leafs. Going with a stock diameter coil is were the time saving/money savings is.

considering he has a 98+ IFS truck.....any SAS is gonna be alot of fab work....but in this case leaves would be easier....

plus, he never mentioned he was goin for a buggy anyways....

Sounds to me that you need to post them pictures to see if maybe it is a Dana 30 and not a 44.

I have a 98+ IFS rig as well. I vote coils **** simplicity it will perform better

Depends pretty easy to check if its 5 on 4.5" its a D30. 5 on 5" can be as well but they are a little more rare and just as strong as an EB D44.

I have YJ leafs on my Ranger....they flex real good. I did add a leaf to help with the weight of the 4.0 and the A4LD. Hasn't sagged yet.

If it is a Dana 30 from an early bronco it will be 5 on 5.5 not the 5 on 4.5.

I thought the Bronco was a D27 or 28 not a 30? The D30 I was referring to in my post was a JK D30 with 5-760x joints and the bigger ujoints.

the jk dana30 is not as strong as the eb44 in stock form.. but the aftermarket support for them is HUGE. the jk dana30 is a slightly glorified d30, period.
