Vehicle Compatibility
The Energy Suspension 3.1108R is designed for select GM vehicle applications.
Always verify:
- Year
- Make
- Model
- Engine
- Transmission
- Mount style
before purchasing.
Hyper-Flex® Polyurethane Construction
Energy Suspension’s proprietary Hyper-Flex® polyurethane is engineered to outperform conventional rubber.
Benefits include:
- Superior wear resistance
- High load capacity
- Excellent resistance to compression
- Long service life
- Consistent performance under heavy loads
Unlike factory rubber mounts, polyurethane maintains its shape even after years of hard driving.
Why Upgrade Your Transmission Mount?
As factory mounts age, they can soften or tear, allowing excessive drivetrain movement.
Common symptoms include:
- Clunking during acceleration
- Drivetrain movement
- Rough shifting
- Increased driveline vibration
- Wheel hop
- Excessive engine and transmission movement
Replacing the mount restores drivetrain stability and improves overall vehicle response.
Improved Drivetrain Control
A polyurethane transmission mount helps:
- Reduce drivetrain flex
- Improve throttle response
- Increase shifting precision
- Improve power transfer
- Reduce unwanted drivetrain movement
- Support higher-performance applications
These benefits become even more noticeable on modified vehicles producing additional horsepower.
Built for Harsh Conditions
Hyper-Flex polyurethane resists deterioration from:
- Engine oil
- Transmission fluid
- Grease
- Road salt
- Ozone
- Heat
- Underbody chemicals
This durability helps extend service life far beyond traditional rubber mounts.
Installation
Typical installation involves:
- Safely support the transmission.
- Remove the factory transmission mount.
- Inspect the transmission crossmember and mounting hardware.
- Install the new polyurethane mount.
- Torque all hardware to factory specifications.
- Verify drivetrain alignment before lowering the vehicle.
Most installations can be completed with common hand tools.
Benefits After Installation
Replacing the factory transmission mount can provide:
- Improved drivetrain stability
- More precise shifting
- Reduced drivetrain movement
- Better throttle response
- Longer service life
- Increased durability for performance driving
