Partial List of Front Torsion Bars

[Marky Dissod]

Here is part of a torsion bar chart batboy found Dec 2017.

my torsion bar adventure - PerformanceTrucks.net Forums

GM Drivetrain & Suspension - my torsion bar adventure - I've owned a 2006 Tahoe 4WD for almost 6 years now and love it. But, I never cared for the tires, they were something called Wildcat A/T Radial (255/70R16). I wanted a couple sizes larger, but could not initially justify getting new one...

Pulled a set out of a 99-02 Z71 Silverado once - don't recall the number or exactly which year, may still have them. They were the same number and not marked differently for LH and RH.

1st guess'd be, torsion bars from any light duty GMT800, should be functionally compatible /
/ functionally interchangeable with any other 1500 GMT800.
But I've been wrong before.
So I think I'm asking:
are Tahoes, 'burbans, Yukons L & XL, Escalades & ESVs, and Silverados & Sierras
capable of using any of the part numbers above ?

If you can glean any more info it'd be helpful, thanks.

Are those chassis codes or option codes listed in the glove box (ex. 6GF) ?

 

[Marky Dissod]

GMT400 (1988 through 2000)
GMT800 (1999 through 2007)
GMT900 (2007 through 2014)
GMT K2 (2014 through 2020)
GMT T1 (2019 through ... )

I found it on my glovebox sticker.

15712407 - LH (6WX) (Max torque 5826)
15712408 - RH (7WX) (Max torque 5826)

These are apparently no longer made and I need new ones. Go figure.

(edit)
These are a tad pricey but would fit the bill it seems. Anyone used these as replacements? The site doesn't seem to list them as a matched pair. All the chassis codes are different between left and right sides that are listed.

Your Tahoe SSV (SEO 5W4?) uses 6WX & 7WX front torsion bars?

 

[Marky Dissod]

@War_Pig,
does your Tahoe use 6WX & 7WX front torsion bars?

Anyone else with a Tahoe PPV or SSV that used
_XM, _WX, _GF, or _YH front torsion bars?
