Review on Timbren Suspension Enhancement System - TORTUN4L: Boost Your Vehicle's Performance by Robert Sisco

Components, steel AND rubber, showed signs of corrosion before receipt. The product stabilized the load well and increased pendulum control. I've used this timbre kit in combination with Rancho 9-speed manual-adjust shocks to boost and stabilize trailer towing. The end of the screw in the rubber spindle would still come out of the ground and hit the frame when hitting big bumps or potholes while towing. I cut the old gel shoe inserts into small 1/4 inch pieces and stuffed them inside the spindles. This kept the end of the bolt in the rubber spindle from hitting the vehicle frame when hitting large bumps while towing a trailer. Pay special attention to the assembly instructions and safety when lifting the vehicle. I couldn't install it exactly as described in the instructions. I had to completely remove both leaf spring brackets on both leaf springs instead of just loosening them. Make sure your vehicle and rear axles are complete and make sure the axles don't move after removing the U-bolts. Make sure the axles and U-bolts return to the same position they were in prior to removing the U-bolts.
