The Story
Fits: 2001 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM Duramax Diesel with Allison 1000
*Scratch & Dent, Installation was attempted. Sold as is, NO RETURNS, REFUND, OR WARRANTY*
Replace your worn or broken rubber transmission mount with this high-quality product from Energy Suspension.
Energy's replacement transmission mounts are the best of both worlds! Soft enough for street use, yet strong enough for racing or off-road use. The mounts for General Motors vehicles have a unique and patented metal safety locking feature to effectively control torque. The interlocking feature of the mount gives added confidence against drive train and chassis/frame damage. This feature delivers the extra strength to resist problematic torque forces.
Unfortunately, General Motors still is using a rubber version of this mount without a safety locking feature (the same type since 1956)! We believe all of our mounts are superior to original factory types.
Energy's special formula HYPER-FLEX performance polyurethane material that is used assures long-lasting performance, unlike many O.E.M. rubber components.
Features:
- A true performance application component for your Duramax strong enough to handle the power of your truck yet soft enough to be comfortable in a street application. Assemble to the chassis the same way as the OEM parts.
- Soft-running enough to absorb vibrations for street use yet rugged for racing use.
- Helps control the massive torque on your Duramax.
- Maintains proper drive shaft angle to help prevent early wear and unexpected power train damage.
- Replaces the original, short lived and too-soft rubber mounts.
- Made of HYPERFLEX performance polyurethane.
-
Resistant to under vehicle fluids such as: oils, coolants, road contaminants, etc.
