Marmon Ride Control (formerly DEA Products) has been a trusted manufacturer of engine and transmission mounts for over 30 years. Marmon Ride Control uses the highest quality of raw materials available, and thoroughly tests their products with state-of-the-art lab equipment to ensure that you'll be installing a mount that will meet or exceed your original mount's specifications.

Testing Includes:
  • Visual Inspection
    • Visual / Finish
    • Paint / Rubber Appearance
    • Weld Integrity
  • Dimensional Verification
    • Dimensions tested / approved using CMM (machine which takes readings in six degrees of freedom and displays these readings in mathematical form)
  • Elastomer / Durometer Tested
    • Rubber Hardness Check
    • Every shipment inspected thoroughly
    • Supplier verification on site
  • Rubber Tensile Strength tested
    • Strip sample and test of rubber processing
    • Supplier must submit test report and sample from every batch
    • On-site audits to verify process capabilities
  • Thermogravimetric Analysis
    • TGA / Rubber Compression Tests (changes in physical and chemical properties of mount materials are measured as a function of increasing temperature (with constant heating rate), or as a function of time (with constant temperature and/or constant mass loss))
    • Rheometer / Vulkameter tested (measure the way rubbers respond to applied forces)
    • Supplier must submit test report and sample from every batch
    • On-site audits to verify process capabilities

Tips & Tools For The Repair
  • Inspect Motor Mounts (found in the "Engine" category) for signs of wear. Transmission and Motor Mounts typically wear at the same rate
  • The original mount bolts can be difficult to remove. Apply Penetrating Oil and have a Breaker Bar handy to help break them loose
  • Find a solid part of the transmission to place the Jack under. Do not use the fluid pan, it is not strong enough to support the weight of the transmission
  • Apply Blue Threadlocker to mount bolts prior to installation to prevent backing out due to the high vibrations transmission mounts are subject to
