If anyone is looking for brand new torsion bars for your 95-05 s10 blazer or truck, I found this seller on eBay last year and I even bought a set for my 95 s10 blazer 4x4. I have no affiliation with the seller.
I have been looking for new torsion bars for over four years and I finally found some. This is a once in a lifetime purchase. Once they are gone there gone. I also belong to the s10forum..com and have made a post there about them also,been a member since December 2022 there. I hope this helps anyone looking for this part.

 

Why would one need to replace them? My stock ones push my blazer higher then my rear leafs with keys backed out all the way. Have 2.5 RO lift.

 

I discovered that my t-bars had sagged when I measured my suspension height and found it was at the stock height even though I had cranked the t-bar adjustment to the maximum.

 

Christine is right. Like any spring, they sag over the years from supporting the weight of the vehicle, to the point where for some people even maxing out the factory adjustment screws won't bring it back to factory ride height, let alone a small lift.

Deadmetal: Congrats on finding new ones! I've seen people looking for new torsion bars regularly, but I've never seen anyone actually find them. You caught the unicorn!

 

So about a year ago I created a suspension parts cross-reference for my own use when I knew I had to replace my rear springs and torsion bars to help me figure out which parts were which.

According to my research the torsion bars you found appear to be for the ZW7 suspension. I might have purchased mine from the same vendor as I could only find the ones for the ZW7 and that is the suspension that came stock with my Blazer.

I've attached a pdf of my cross-reference.
