Torsion bar help

[joesnextoy]

Ok I have a 99 burb 4wd and I'm looking to swap out the torsion bars
I am mounting a fishing cooler rack that will slide on and off like a trailer hitch receiver it holds 3 coolers so when I'm loaded with ice, bait and food it all adds up
SOOO I want to know if I swap in 2500 torsion bars would it hold the weight better and if so how to I figure out which ones to get or can I get them from any 2500 up to 2006 ???

Thanks!!!!!

Torsion bars are part of the front suspension. You may want to look into air bags for the rear.

The cooler rack gets attached to the front of the truck , I have the rear covered already

Look up your torsion bar RPO code on the sticker in the glove box door. That will tell you what you have, if it is original to the truck and still legible.


" The bar RPO's will be a three digit code, something like "RGK or "LGK" where the second two digits are of course the bars letters."CHEVY TORSION BAR CODES AND RATINGS:
