3" spacer lift after a suspension lift

[BigPaw]

Trying to figuer out if a 3" spacer will give me the right amount of rake after installing a suspension lift with a heavy load in the rear.

I've read that after installing a suspension lift, people install a 2" spacer lift to level out the rear end.

I carry heavy weight in the back from time to time and wanted to know if a 3" spacer will work better for those heavy loads from not looking like a dumped rear end when under load. If a 2" spacer levels out the rear end under no load, wouldnt that make it sag if it was under load?

What say you?

Yes depends on lifts, what kit?

Look up timbren

I am assuming you dont have the rear air leveling shocks...

If you do, and everything is adjusted properly, you should be just fine with a level ride as the shocks will level it back off when you add the load.

If not, well yes, when your vehicle is level without a load and then you add a heavy load, it will end up low out back. That is not rocket science.

Is you vehicle level now with no load? Do you have rear air leveling shocks?

No rear air ride shocks, looks level with out a load, but Im just trying to avoid it from sagging when under load.

So will a 2" or 3" achieve this?

Honestly, without air assist there is really no way you can achieve both. If its level without a load and you load it, it will sag. If its level with a load and you unload it, it will be high in the back.

Timbrens will definitely help, but they are not the complete answer in my opinion.

If you are really picky, as I am, install air bags. Thats what I use on my truck. It is level with no load, and when I hook up to any trailer or haul any load, just air up the bags to make it level.

The cheapest easiest method would be to add helper bags inside the longer springs. This will allow it to be normal height unloaded and air up for towing. Firestone or air lift can help determine the right bag size depending on spring size.

Thanks gents! I dont mind it being a little taller in the rear when unloaded, but I didnt even think about air bags. Will have to consider them then.

If you are using shock extenders in the rear with stock size shocks you could get Monroe Max Air adjustable shocks.
http://www.monroe.com/en-US/products/Max-Air/shock-Absorbers
I have been running them for years on vehicles for towing and vehicles with large stereo systems. 1,100lbs capacity good from 20psi - 150psi, run them down around 50-70lbs for leveled daily use, put load on vehicle hit them with an air compressor until the rear is level again. They do offer them in different lengths and you could use Monroes online database to see if there is possibly a shock with the correct mounts, extended length, and compressed length to fit with the lift with out shock extenders.

Those might work! Hows the ride level w/o load and loaded air'd up?

I looked today and they only have a stock length and shorter Max Air that fit our mounts, so you would need to use shock extenders with stock length Max Airs. I loved the ride, When I would air it down w/o a load it was nice and smooth, I could also air up to get an inch or so lift and have a stiffer ride with less body roll. With loads I would always hitch my trailer or load the back up then air it up until it was back to normal ride height or the trailer was level. This always resulted in a planted and controlled feel, still smooth over bumps but not bouncy at all, very controlled. I’d definitly say Monroe did a great job pairing the shocks valving to the air bag.

I watched vids on them and they look promising. Thanks for the info sir!

Just another idea for you, you could look at the shocks for the premium smooth ride (ZW7) suspension. They are nivomat (self leveling) shocks. Those with shock extensions will pump themselves up (internal pumping done by shock moving during first few hundred feet of driving) to the set height, automatically compensating for the load changes. Can pick up on Amazon for around $60 each.
