Looking to minimize sag while loaded


Recommended Posts

I have recently been carrying loads that are right at the rating for my '99 1500 Sierra and am finding the rear sags siginificantly as I aproach the max load rating. I have read many threads about adding leafs, helper springs, load leveler shocks, 2500 springs, but what are peoples thoughts on a long term solution that will not compromise unloaded ride quality, but keep the rear end up when loaded. I do some towing, but my primary concern has to do the carrying gravel, dirt etc.

 

Thanks,

Jay

I think that the add a leaf deal doesn't engage until loaded. You could also consider some air bags. I've heard good things about the firestone system. Pressure can be increased or decreased with a wireless remote, and you can preset certain weights or settings for certain loads.

Edit: I "thought" that the add a leaf system was passive until the other leafs lowered to it, but KMGZ400 would know better than I would.

Thanks Guys, and as I understand things-

The add a leafs seem like the most inexpensive way to go, and since I am not concerned about changing the ride height may be a good solution. However, they may change ride quality slightly.

 

For the bags, they look more expensive and installation will take a bit longer, but will allow for custom settings depending on my load. How often (if ever) do the bags/hoses need to be replaced?

 

The timbrens are new to me and look very simple to install, and are priced in between the add a leafs and the bags. How long have they been around and how is their reliability?

I have Timbrens on my truck. They work great for the loads I tow and haul. I do not even notice them when driving unloaded on rough roads. The only negative is that with lighter tongue weights, the springs will not settle into the overloads. Makes for a little more motion and movement while driving... But once I get past 600-700 pounds on tongue weight, they are awesome...

This is what I would love to have...if I had the money.

They sound great, no harsh ride and only apply as the load increases.

 

 

However, I'm currently looking to add something along the lines of helper springs since they are much cheaper sorta like the Superior 11-1020 kit. Either way I have to wait under the funding committee (wife) gives me an approval to purchase...lol

Thanks for all of the input and it has been enlighteing.I am now trading off all of the pros/cons and prices to see which approach makes the most sense for my application.
