I was wondering if anyone has awesome experience with load helpers? I’ve got a ‘99 k3500 that sits lower then I’d like with a load.

I started using felling wedges between my overload and springpack from time to time. It’s helps on the heavy loads tremendously. It’s only been a recent temporary solution. I came across this trying to mimic a product I’ve come across in the past.

I’ve looked at a couple different helper springs, like Helwig and SuperSpring. And super spring has the sumo blocks or whatever they call them, that kind of simulate an air bag but is just a poly foam block. I’ve also wondered about finding dually upper overloads and putting them on my truck.

My truck is still handling good, though I wouldn’t mind a little more stiffness, but mainly I hate the sag I get with trailers I feel shouldn’t drop my truck so much.

One thing also, I guess any experience with one that doesn’t chatter your teeth when you’ve not got a load.

Air bags will add 5k to your suspension, and it's soft and adjustable.

I agree. I had air bags on my 2000 gmt800 and that was the best thing ever. Nice ride empty and no air pressure. Rode very good with a hefty load and enough air to equalize the load.

I don’t have it on my truck, but would like that the best I think. Pretty sure that’s a stock thing for DRW, my truck in a single wheel 3500.

I was under the impression that all 3500s got it seeing how the SRW trucks were rated 9200 vs a 2500 at 8600 GVWR. You'd need the frame dealies that bolt on that the uppers engage under load too.

I know for sure the 3500 DRW (GVWR = 10,000 lbs) have the overload spring. My 3500 SRW has a 6 leafpack. I "think" the 2500 have 5 leafpack?

OP, how much load are you putting back there? Tongue weight + payload weight. The most I've put on mine is an entire pallet of concrete bags. 42 bags @ 80 lbs = 3,360 lbs. Pretty good sag.

I came across these:

I'm interested as well on doing something similar. Let us know what you select.
