For RV and trailer owners, the comfort and durability of a journey are often dictated by the performance of the suspension system. The Equa-Flex and Red E-Z Flex systems are two suspension solutions designed to improve ride quality by reducing road shock and equalizing weight distribution across axles. These systems are particularly valuable for those who frequently travel on rough or uneven terrain, as they help preserve the integrity of both the trailer and its contents. This article provides a detailed overview of the technical specifications, performance characteristics, and practical considerations for installation and maintenance of these systems, based on information available from official and user-submitted documentation.
Overview of Equa-Flex and Red E-Z Flex
Equa-Flex and Red E-Z Flex are both designed to replace traditional leaf spring suspensions in trailers and fifth wheels. Each system aims to reduce vibration and road shock while maintaining or improving load distribution. These systems are particularly beneficial for trailers with axles rated up to 8,000 pounds and are available in retrofit kits or as factory-installed options.
Equa-Flex, according to one user testimonial, completely replaces the standard rigid double-eye leaf spring suspension used on two- and three-axle trailers and fifth wheels. It functions similarly to rigid equalizers by allowing the same rotational movement but with added cushioning. On smooth roads, the improvement may not be noticeable, but on rough or unpaved terrain, the difference in comfort and damage prevention becomes more apparent.
The Red E-Z Flex system, developed by Dexter Group, incorporates a patented rubber insert that is scientifically formulated to provide optimal dampening. This design allows for continuous pivoting and compression, which isolates and absorbs road shocks before they are transferred to the trailer frame. According to Dexter, the Red E-Z Flex system provides up to an 80% reduction in acceleration forces on the trailer frame compared to a standard equalizer.

Both systems are marketed as alternatives to traditional leaf spring suspensions, with a focus on reducing wear and tear on trailers and improving ride quality. The Red E-Z Flex system is noted for its durability, long warranty, and ease of installation, making it a popular choice for both DIY and professional installations.
Performance and User Experience
User reports and technical documentation highlight the performance benefits of Equa-Flex and Red E-Z Flex systems. On smooth roads, the difference in comfort may not be as noticeable, but on rough or unpaved roads, the cushioning effect becomes more apparent. This is particularly important for trailers carrying sensitive cargo, such as horses or valuable equipment, where sudden jolts can cause damage or distress.
One user noted that the Equa-Flex system allows the trailer to absorb road shocks effectively, reducing the likelihood of items tumbling off shelves or damaging internal structures. Another user, who had experienced issues with their Equa-Flex system becoming misaligned after jacking up the RV without using the axles, received advice on correcting the alignment using a floor jack. The process involved correcting the shackles and ensuring the system realigns properly.
The Red E-Z Flex system is also praised for its ability to handle rough roads without transferring significant shock to the trailer frame. This helps preserve the structural integrity of the trailer and minimizes damage over time. Additionally, the system's design includes features that reduce suspension noise, which is a common complaint with traditional leaf spring systems.
Installation and Retrofit Considerations
Both Equa-Flex and Red E-Z Flex systems are available as retrofit kits for existing trailers or as factory-installed options for new builds. Installation typically involves replacing the traditional leaf spring suspension with the Equa-Flex or Red E-Z Flex system. The process is described as relatively straightforward, with the Red E-Z Flex system noting that it will not alter the ride height of the trailer compared to competitors' systems.
For users considering an upgrade, it is important to assess the condition of the existing suspension components. One user encountered issues with a sheared-off bolt in the Equa-Flex system, which complicated the installation and maintenance process. They noted that the bolt was difficult to remove and suspected corrosion or seizing. This highlights the importance of inspecting all components before installation and ensuring that all hardware is in good working condition.
The Red E-Z Flex system is also designed with ease of installation in mind. It features heavy-duty greaseable shackle links and a durable red powder coat finish, which should reduce the frequency of maintenance required. The system’s 5-year limited warranty provides additional reassurance for users looking to invest in a long-term solution.
Maintenance and Troubleshooting
Maintaining the performance of Equa-Flex and Red E-Z Flex systems involves regular inspection and lubrication of key components. The Red E-Z Flex system includes greaseable shackle links, which should be lubricated periodically to ensure smooth operation and prevent corrosion. Users who experience issues with misalignment or bolt seizing should carefully inspect the hardware for signs of wear or corrosion and take appropriate corrective action.
One user reported that their Equa-Flex system had bent the center hanger, which they suspected had compromised the system’s integrity. They were advised to replace the center hanger rather than attempting to straighten it, as bending could weaken the structure and reduce its effectiveness. This highlights the importance of replacing damaged components rather than attempting to repair them, especially in critical suspension systems.
Another common issue reported by users involves bolts shearing off or becoming stuck due to corrosion. In such cases, penetrating oil and gentle tapping with a wrench can help loosen the bolt, but in severe cases, replacement of the bolt may be necessary. It is also important to ensure that all hardware is compatible and properly torqued to prevent future issues.
Warranty and Support
Both Equa-Flex and Red E-Z Flex systems offer warranties that provide additional protection for users. The Equa-Flex system comes with a one-year warranty to the original owner, while the Red E-Z Flex system offers a 5-year limited warranty. These warranties cover defects in materials and workmanship but do not typically extend to damage caused by improper installation, misuse, or failure to maintain the system.
One user inquired whether their 2013 trailer would be covered under Lippert’s updated warranty. While the response was not confirmed, it is important for users to review the warranty terms and conditions provided by the manufacturer or retailer. If the suspension system is part of the original equipment, users should contact the manufacturer for clarification on warranty coverage.
Conclusion
Equa-Flex and Red E-Z Flex suspension systems offer significant improvements in ride quality and durability for RV and trailer owners. These systems are designed to reduce road shock, equalize weight distribution, and protect both the trailer and its contents from damage. With features such as easy installation, long warranties, and proven performance on rough terrain, these systems are valuable upgrades for those seeking a smoother and more reliable towing experience.
Users considering an upgrade should carefully assess the condition of their existing suspension components and ensure that all hardware is in good working order. Regular maintenance, including lubrication of greaseable parts and inspection of hardware, is essential for maintaining optimal performance. In the event of misalignment or hardware issues, users should follow the manufacturer’s guidelines for troubleshooting and repair.
Ultimately, the choice between Equa-Flex and Red E-Z Flex depends on the specific needs and preferences of the user. Both systems offer distinct advantages, and users should evaluate their options based on factors such as compatibility, performance, and long-term cost.
