Rear sway bar mounting: Calling Donivan

Post by Digz on Tue Jun 23, 2015 6:58 pm

I have been sitting on this for a while now and have finally decided to put it on.

I tried the Search and really I have had limited luck using it. I know there are pics out there somewhere? Next is locating the frame mounts for the end links. Where should they about end up?

let me go find some of it,,,,,,,I also put air bags back there to support the frame since I don't trust the shackles to hold up when I put 2 tons of stuff in the van,,,,,,

My van is jacked up in back, so I used a longer carriage bolt for the link,,,,,,I made an extension for the frame for the upper link bracket,,,,

Thanks Don ! That's what I needed to see. I didn't really like the idea of welding more to the frame. That saddle mount style should fit the bill. Good chance I'll have to swap to some longer links also.
Thanks again.

Looks like your brackets are backwards putting too much side load on the end links

Well,,,,,these vans did not even come with front sway bars let alone rear ones,,,,,they are used on coil spring suspensions to prevent leaning on turns,,,,,,,this one is off a 85 Firebird, costing $11,,,,,I think my rear sway bar has an easy life back there,,,,,I have a front sway bar, 7 leafs in the rear springs, and rear air bags,,,,,,so I doubt those links ever get any use,,,,,,if there was a problem, I think the link would bend the frame bracket into a different position,,,,,,,

you can modify the upper bracket if you want the link to be perfectly vertical,,,,but using the Firebird/Camaro bracket was close enough for me......and I have probably bent my brackets with all the stuff I haul anyways,,,,,,,

I still have a chunk of 3 x 6 box tubing I will cut up for the frame wrap and possibly the drops if clearance allows. Did you just run some 5/16" or 3/8" bolts thru the frame Don ?

The sway bar is really a torsion bar,,,,,made to twist when one link pushes down on one side which causes the other to pull the frame down as the van leans,,,,,they are like a rubber band,,,,,so basically they are there to keep the van standing straight up,,,,,I doubt that there is a lot of pressure on everything back there,,,,I used 5/16" bolts right through the frame,,,,,,2nd Gens are kind of like riding on a waterbed with their soft springs,,,,and you got the HEAVY DUTY 3 leaf ones,,,,,,they surely can use sway bars,,,,,,SportVans are the ones that come with front sway bars,,,,,our 1st Gens ride pretty rough with their 6 and 7 leafs in back,,,,,,the link spacers are made from 1/2" solid electrical conduit
