http://kinetikpower.com That right there would be the ideal setup for your toyota. It's simple, doesn't take much space It's not too fast and it is RELIABLE.

Hydraulics are making a come back, and strong. There were a few of us that never gave up on them, especially Hydroholics, and look what they managed to turn them into now. I HIGHLY reccommend Hydraulics over strut bags. I've had both, and I will never ever return to air ride again.. Check out a few of the build threads on here... Search "Hydroholics" You'll be amazed at what you see.
