Energy Suspension Hyperflex Polyurethane Transmission Mounts

Energy Suspension's Hyperflex Polyurethane transmission mounts are much more durable, and better-suited material for handling the stresses of a transmission. Polyurethane is unaffected by UV rays, road grimes and vehicle oils, ensuring a long-lasting lifespan and performance.

>Energy Suspension Hyperflex Polyurethane Transmission Mounts

The Problem, The Cure

The O.E. transmission mount is made of soft rubber. While the rubber is good for dampening noise and vibration, it is susceptible to cracking and splitting. Without a proper functioning transmission mount, excess transmission movement is allowed as well as dangerous torque movement. Energy Suspension's polyurethane mounts are much stronger than the rubber and is not prone to cracking. With the polyurethane transmission mounts, you will have controlled torque and the excess movement will be eliminated.
