Review on 🚀 Enhance Performance and Stability with PROTHANE 7-1604 Red Urethane Transmission Mount Kit for 6 and 8 Cylinder Engines by Matthew Sutton

Much better than energy suspensions! It's wider and stiffer, has butt height and doesn't require a preload plate. I put it next to the energy plate and with the preload plate the energy plate was taller, without it it was shorter. This one is much easier to install as it has an Allen screw and bolt that locks it in place. Simply insert the screw with the bolt already on it, tighten and then tighten the bolt. Bought the Energy version to replace my broken stock mount with a 98 z28. The gearbox vibrated immediately. Tried with and without the preload plate, upgraded to UMI Torque Arm Move Bracket, upgraded to UMI Adjustable Torque Arm and replaced the Power Reaction Arm socket with the included Prothane socket. There was also vibration. Bought this and it's gone.
