overload shocks or helper springs??
Hello, 1999 GMC 1500 Sierra 8400lb towing capacity. Towing 2010 Jayflight 6500lbs. The truck is a 2wh drive so sits a bit low, currently stock shocks on it. I'd like to give just a smidge of lift ...

brulaz, it is because of what you said that I do not recommend using rear suspension aides with a WDH. That is typically all one needs, a properly adjusted WDH. Rare cases when someone has a heavy pickup bed load and a heavy TT, but that's not likely the case for any half ton.
My half ton squats until I put the bars on, then it lifts back up almost to unloaded. My tongue weight is about 750 lbs, plus the WDH, plus the bikes in the back.
With just the bars in position, the lift is great, but there is a lot of bounce between the truck and trailer at the pivot point.
When I added air bags (airlift) into the back end, the sag was only about half as bad. With the bars in position, the lift is again almost back to unloaded (without any adjustment to the chain position, just to the ball angle) but the bounce between the truck and trailer is nearly gone.
The ride with the airbags inflated and truck unloaded is very rough, but it is easy to decrease the air pressure and put the ride back to normal.
