Rearend setup on my project. I know somethings wierd?

[stevo427]

So whats up with these bars under my leaf springs? Guy I bought it off said they where some sort of old ladder bar setup. The rear end is an 8 3/4 489 with a sure grip. The yoke spun 3 3/4 times for 1 tire spin so I'm guessing its a 3.91 (Which would be awesome). Help? haha

In this picture I was wondering if the 4-speed trans crossmember was still intact. Someone swapped in an auto

and cats seem to think the roadrunner is a bed :loco:

P.S I was glad to find out the runner has an undercoating and when chipped off reveals nice black paint. Everywhere i chip it off the underside looks new. It's covered in this under coating.

Thanks for any help

Those are some old traction bars and the rubber snubbers are gone off the front. They worked ok on mopars but it was much easier to put a pinion snubber on top of the diff which worked well and was sneaky, out of sight.

Those are traction bars on the springs.

Sweet thanks. So it's safe to say all of my original rear suspension is still intact other then these traction bars?. All I'd have to do is install some rubber snubbers and they'd work fine?. I'm new to mopar style suspension. A lot different then trailing arm style trucks. and whats with the shock absorbers? Couldn't really see where they would mount up to.

Or could I just remove them. There kind of ugly looking and from what I read they dont help much on a mopar like you said.

They don't help at all.

They were used on GM cars to prevent wheel hop. The long front section of a GM leaf spring would curl up under acceleration and actually pull the tire up off the ground. Then when traction was lost, the tire would drop back down, catch traction again and the spring would curl again. On and on, causing the tire to "hop" up and down.

Mopars didn't need the bandaid. The leaf spring had a shorter, stiffer front section. No wheel hop.

Problem was some of the Mopar guys did their best to copy the GM guys... So when K-Mart had a sale on yellow traction bars, the uninformed went out and spent their paychecks.

You will need a set of shock mounting plates - your original ones are gone - replaced by the GM slapper bars. Hit e-bag or the local swap meet. Not hard to find. Someone on here may even have an extra set that they will sell you.

I bet the u-bolts need replaced also.

If you're going with stock type suspension, and looking to improve traction, I'd go with the super stock springs.
:cents:

hard to tell on the crossmember, post up a shot of it from the front. the 4 speed member looks the same front/back. the auto has an extra piece...towards one side for the rubber mount, where on the 4 speed it's inside the member. I might have an extra set of the shock plates. Let me know and I can look this weekend.

Alright I'll get a picture of the front when I get off work. And that'd be awesome

 

[stevo427]

Looked at my rear cross Member where the shocks hook up to and it's pretty torn up. So I'll add that to the list of stuff to eventually get also haha

 

[Basketcase]

yeah mine was tore up pretty good when I got this car. lucked out and got one at the boneyard for $25. AMD (and others) sell them new.

 

[stevo427]

Was hoping so. Finding mopar parts at junkyards down here is pretty rare
