Adding rear sway bar to 99 suburban

[phantom309]

With the extra forced upon me spare time that i now have,..
I have puttering on our suburban,. I would like to add a rear sway bar.
Has anybody here done this already and blazed a path i can easily go down?

Nick:

My 2010 Avalanche (shares the same chassis with the burbies) has both a panhard rod and sway bar. Might be able to adapt those for your 99.

Stay safe.

So,. After some googling,. I have found out i' m not actually looking for a sway bar,. But a stabilizer shaft gm# 15640308. For 1992-2000 K 3500 cab and chassis.
But,. The plot thickens,. Fleabay has some but shipping weak looney buck etc final price is just silly, and i'm poh.

After finding the part i need i just buy it from gmpartsdirect in canada,.
But that part# does not work,. It works on a google internet search,.

The avalanche bar is shaped wrong to work with the 10.5 banjo and leaf springs,..

Hah mystery solved,. Oart has long been dicontinued so the fleabay bars are nos,.. unfortunately Texas to me shipping is silly.
So when the gummint sees fit to let the hordes back into the junk yards,. I shall go on a quest,...
So back to your regularly scheduled chinese virus programming.

We followed a late 1990s Suburban on the freeway for a few miles the other day, and I noticed that it had a rear sway bar... I daydreamed a bit about adding one of those to my Lil Red project...

I think the automakers added rear sway bars to help prevent rollovers... Good idea!

Mine is the 1500 with coils but I do know some of the earlier ones were available as a 2500 (leafs??). The earlier ones were available with the 454 and the Allison so these might cross to the correct sway bars/panhard.

Stay safe
