I have a 90 4runner and as we all know it comes with the BS 4link. I have extended the lowers 28'' and mouted them under the frame rail. I ditched the uppers and made a single 1 1/4'' solid steel link with 30,000 lb heim joints witch run from the center of the pumkin up to the factory crossmember. I plated and braced the crossmember for added strength. I also relocated the rear shocks for more travel. When drooped I can set another 36'' swamper on top of my 36's and still have fender clearence. The truck looks broken when it is flexing it flexs so much. This truck is my daily driver and weekend worrior. I currently have leafs in the front witch are my weak point at this time. I am working on a triangular set up for the front so I can get the front to work as well as the rear. The key to a street driven link rig is in the swaybars, if you have them great but you need quick discos, and if you don't have them hold on cause every corner you turn is an adventure.
