Vehicle Compatibility
The Energy Suspension 7.2103R is designed for select Nissan applications.
Because compatibility varies by chassis and suspension design, verify your specific vehicle using the manufacturer’s application guide or part lookup before purchasing.
Hyper-Flex® Polyurethane Construction
Unlike conventional rubber bushings, Energy Suspension uses its proprietary Hyper-Flex® polyurethane material.
Benefits include:
- Excellent wear resistance
- Higher load capacity
- Reduced deflection
- Improved durability
- Long service life
Polyurethane maintains its shape better over time, helping the suspension perform more consistently.
Superior Resistance to Contaminants
One of the biggest advantages of polyurethane is its resistance to environmental damage.
The Hyper-Flex material resists:
- Oil
- Grease
- Road salt
- Chemicals
- Ozone
- Moisture
- Road debris
Unlike rubber, polyurethane is far less likely to crack, soften, or deteriorate from exposure to contaminants.
Improve Suspension Performance
Replacing worn rear spring bushings helps restore suspension operation.
Potential benefits include:
- Improved suspension stability
- More consistent spring positioning
- Better handling response
- Reduced suspension flex
- Longer component life
These improvements become especially noticeable on older vehicles with deteriorated factory bushings.
Ideal for Street & Performance Builds
The Energy Suspension bushings work well for a variety of driving styles.
Recommended for:
- Daily drivers
- Restorations
- Lowered vehicles
- Performance street cars
- Autocross builds
- Track-day vehicles
Their increased stiffness helps maintain more consistent suspension geometry during aggressive driving.
Installation
Replacing rear spring bushings typically involves:
- Safely raise and support the vehicle.
- Remove the rear suspension spring assembly.
- Remove the old rubber bushings.
- Clean all mounting surfaces.
- Install the polyurethane bushings using the supplied lubricant (if included).
- Reassemble the suspension and torque hardware to factory specifications.
Professional installation is recommended if suspension disassembly is required.
Benefits After Installation
Installing polyurethane spring bushings can provide:
- Longer service life
- Better suspension consistency
- Improved handling precision
- Greater resistance to wear
- Reduced bushing deformation
Pros
- Durable Hyper-Flex® polyurethane construction
- Made in the USA
- Longer lifespan than factory rubber
- Excellent chemical and oil resistance
- Improves suspension consistency
- Performance-oriented design
- Suitable for street and motorsports applications
- Helps reduce suspension deflection
Cons
- Firmer than factory rubber bushings
- May increase road noise and vibration slightly
- Vehicle-specific compatibility must be verified
- Professional installation may be preferred for some applications
Final Verdict
The Energy Suspension 7.2103R Rear Spring Bushing Set is an excellent upgrade for compatible Nissan vehicles requiring replacement rear spring bushings. Constructed from Hyper-Flex® polyurethane, these bushings provide superior durability, greater resistance to oil and road contaminants, and more consistent suspension performance than traditional rubber bushings.
Whether you’re restoring an aging suspension or upgrading for improved handling, the 7.2103R delivers a long-lasting solution that balances durability with enhanced suspension control.
