Review on Engine Optimization Spring Assist by Jesse Diaz

These over the axle assist coils seem like a good idea but after installing a 92 g20 in my van I found them to be springy and now, annoying when the van hits the ground with compressed springs. Everything was fine at first as they lifted the sagging bed of my overloaded van. Then a few days later, on my first drive down one of our bumpier freeways, I ran over a couple of bumps that caused the van to tip over in a series of 3 bumps that knocked the passenger side spring right off the axle . Luckily I installed the stop plate on the mount and although the spring shifted it didn't hit the ground and killed a poor rider behind me. The remaining spring made my life miserable all the way home as my van now looked like a crazy pogo stick and the driver's side was bouncing almost uncontrollably. I removed the auxiliary springs and installed this "Add Leaf" kit available here on Amazon Explorer Pro Comp 13120 Short Add Leaf Kit and these air shocks are also available here on Amazon. Monroe MA817 Max-Air Air Shock Absorber Still not perfect, my van is better.
