I needed new coil overs for my 2011 4Runner with KDSS. Front suspension had sagged 0.75 inches. A local off road performance shop would not guarantee their work when I requested a 1-inch lift, by citing a potential risk for KDSS lean. In other words, their mechanic doesn’t know how to work on a vehicle with KDSS.
I’m retired and a bit stubborn, so I got it in my head that I could make a spring compressor. It utilizes the 4Runner’s screw jack to compress the spring. Spent $40 on all thread rod and nuts. The rest is steel and aluminum from a metal scrap bin, and parts on hand. Assembled and installed the new coil overs, achieving 1-inch lift and did not encounter any issues. KDSS system is balanced and there is no lean.
