Super spring

What are you trying to accomplish? Rear end too low? Compensate for PIN weight? More info please.

I use these folks for all my truck suspensions upgrades.

Give them a 1-800

They make air bags, but not knowing what your issue is they may not help.
Firestone air bags

If you need to modify the suspension for the load you do not have enough truck. Add springs, air bags, timbrens or anything else the bottom line is you still have a half ton truck and you should have bought bigger 2500?

Yes, they make lipstick for pigs.

But as the old saying goes, you can put lipstick on a pig...

Missed your new member status....but welcome to the forum.
Your a brave person for coming on a rv website and mention a 1500 truck pulling a 5th wheel trailer.
For whatever reason some rv folks don't think a 1/2 ton truck can pull a 5th wheel trailer.
Anywayz give etrailer a call and be sure to include your GMC trucks ARC package. I'm sure they have other customers with trucks and ARC systems.

Thanks to everyone that offer good advice putting Timbren on should help with sagging.
I had a Chevy 1/2 ton since 2013 with max trailing package with super springs putting a 5th wheel never had any problems.

Yes, there are so many people here just waiting to jump on somebody to tell them what they can and can't do.
You can't tow a 5er with a half ton.
You can't tow a 5er with a 2500.
You can't tow a 5er with a single rear wheel 2500.
You MUST only tow a 5er with a 3500 dually. :h

Oh yeah, I forgot to mention the weight police circling like sharks ready to attack. ;)

I thought it was:
You can only tow a 5er with a Kenworth

:S
