Spring under rear axle conversion.

'87 Dodge D150

Is it possible to relocate the axle to the topside of the leaf springs to lower the truck?
If so, what all is involved in doing that?

Just eyeballing it, it seems like there's not enough arch in the leaf springs to give you room between the axle and the frame if you do flip it, but I've heard several people recommend this as a way of lowering the truck.

Any help?

axle flips are NOT recommended!!!!

I'v raised older jeeps like this and they ride like log wagons.

Wont track straight and plenty of bounce.

Wouldnt do it again.

I know...same principle. I dont recommend it....

I would try EVERYTHING else I could before trying this.

IE: Remove a leaf from the spring

Ok, so you went from a spring under to a spring over (raising it) and handling and ride got worse.

I'm wanting to go from spring over to spring under (lowering it), and you saying it will have the same effect as raising yours did?

I'm really not seeing your logic here.

Removing a leaf would be a very small drop, plus it would make axle wrap even more of a problem.

I have seen it done before, never heard of any negative consequences. On yours there may not be enough room for suspension travel with the relocation, a C-notch may be required.
I have a 99 Dakota that I lowered, I had new spring hanger mounts made to achieve part of my drop, maybe it would work for you.

You may have to c-notch the frame. This is a 58 Chevy truck I did for someone. And there is nothing wrong at all,When done right.And you will not notice any difference in the ride at all.(When done right) Lifting and lowering a vehicle is two different thing's.You will get a different ride when lifting a vehicle.

re:spring under rear

I have done several fllps as well no change in ride , but as others have said you may have to do a C notch.

You can make one your self or take a look in the ads in mini trucking or trucker mag's. you can buy allmost everything you need.

Unless you are like most of us and either have to or want to do it your self.

The other things i did to lower a buddy's mazada pickup were to remove one leaf and moved the rear leaf spring mount up higher on the frame, I dont know how they are on a dodge.

Now dont forget the front whats your truck have coils or torsion bars?

Coils in the front.
I've been told that Dakota drop spindles will work without too much effort. So I'll probably go that route.

My bro and I did a 4/6 drop on his short bed Chevy, which is
basically what you want on your Dodge, it rides just the same,
we did the flip on the rear, with frame notches, and springs and
spindles on the front. It looks very cool with 215/65R15s up
front, and 255/60R15s on the back...

Oh, the frame notches were welded in, not bolted, I didn't trust
the grade 5 bolts they sent with the kit...
