WHERE TO GET??? REAR air suspension for towing????

[MercuryEvo]

Hey guys, I have an 07 4 runner V8 limited with tow package and I tow a 3000 lbs car on a 1500 lb trailor around alot and The truck drives great but the rear squats when the car is on the trailor. Does anyone make an auto leveling rear air bag suspension setup for this truck? Or would just a stiffer rear spring setup do the trick? I just want to keep the truck level when I tow. Thanks in advance

-Steve

Hi Guys, new to forum and new owner of a Salsa Red 4Runner. I couldn't be happier with my purchase. I replaced a 160k '99 Trooper with an '05 Nissan Titan. I missed the Trooper so much I had to get back to a Trooper-like vehicle and settled on the 4Runner for all the reasons we all know...

On my Trooper I used the Air-Lift 1000 in a couple different configurations; stock springs standard install, modified install and finally with OME HD springs. Overall the results were so good I ordered (but have not installed yet) a set for my 4Runner. I just read the great post at www.toyota-4runner.org/showthread.php?s=&threadid=14181&perpage=15&pagenumber=4

What I learned on my Trooper is that for virtually no money you can install 2 air valves, one for the right bag and one for the left bag. What I found is that when loaded you have the option to do some right/left balancing. The big advantage was that when loaded (with bags inflated) I gained a good bit of high speed stability. By separating the right and left sides the body-roll was reduced noticeably. As the body tips with a 1 valve system the compressed bags air just goes to the other side. With a right/left separated, 2 valve install the compressed bag just gets stiffer and aids in holding the body level. When the vehicle was unloaded and the bags were at 5-8psi I had no appreciable reduction in rear axle articulation.

I hope this helps somebody, love the forum!

My needs in the past (and present) don't allow for a weight distributing hitch. I will load the inside with gear and then put a motorcycle on a light utility or some combo of that. The other thing I do is tow a boat with dogs and gear in the car. I suppose if you had a permanent setup like a camp trailer or horse trailer, a weight distributing hitch would be great (and necessary). Even if I had a setup like that I'd still like the AirLift for the $100. IMHO:biggrin2:

thanks for the links but would that solve this problem?

Good point. Thanks for the tip. Now I have another spring time mod.

MercuryEvo, based on my Trooper experience and looking at the picture of your rig I would say yes with a qualifier... The 4Runner is a 4Runner, not an F350 dually. I have moved trailers with tractors, palm trees etc that were similar in configuration and weight to your rig with my AirLift equipped Trooper. You WILL still feel the weight. The wheelbase is still comparatively short, the shocks will seem a touch under-dampened but the AirSprings will help tremendously.
