Most Popular Leaf Spring Enhancement System for 2006 Toyota 4Runner

My small dumping trailer was bouncing and swaying all over the place. After installing this shock kit, it follows along like a dream. A more than worthwhile investment. Easy to install, great customer service. Thanks!!!

Not a trailer, but... We needed a set of shocks for a three-wheeled motorcycle truck conversion for our resort/farm in upper Thailand. I had to pack it in my luggage for the trip over. The vehicle came with no shocks on the back axle and the ride was really bad. This kit, with a bit of modification, really did the job and the ride is now significantly better in terms of smoothness and handling. Shocks were a bit long, but it worked out OK.

I made some brackets to bolt to the frame. Now I have 100% contact with the Sumo Springs. The are working extremely well!
