I have an 87 4Runner. Anyone know of an air ride kit for this, or what might work? I use it for work, not really any serious off road. Need the extra help due to the weight of tools and supplies I haul in the rear.

 

I have an Add-a-leaf in the rear of mine, fixed the sag and gave me plenty of extra load carrying capacity. If you have a load in the rear it rides about as well as stock, and without, it's not too bad....no worse than any other leaf sprung truck. Probably much cheaper than an air ride set up. I think I got mine for less than $100.

 

Firestone had and air ride setup for the leaf sprung 4Runners and trucks.
So did AirLift.

Saw em in an NWOR catalog. Not sure if they are still avail...
