Powder Coating Torsion Bars
Can you bead blast t-bars?
I don't see why not, though I'm not sure I would use a super aggressive media because you don't want to damage the surface. But if the surface of the bar is so bad that it needs to be bead blasted you might want to consider new torsion bars. I'd be more concerned with the rust or whatever you were trying to blast having damaged the bars already than the bead blasting causing issues.
Firm feel can recondition original torsion bars. If you look at the link I provided to Firm Feel above it describes the process. From their website - "For customers that want OE torsion bars with correct forge number we offer complete reconditioning. We will take your worn out OE torsion bars: reindex, straighten, shot-peen, and reheat treat back to new condition." Of course, they charge $200 to do it, and at that point you'll still have a factory torsion bar which will result in a factory original undersprung ride. But I suppose if you're doing some 100% original rebuild on some matching numbers rarity it makes sense. Ish.
