After the Test: My Review of Lippert 279689 Heavy Duty Equa Flex Rubberized Equalizer Triple Axle Kit 5 000 To 8 000 Lbs.
My quest for a smoother towing experience led me to the Lippert 279689 Heavy Duty Equa Flex Rubberized Equalizer Triple Axle Kit 5 000 To 8 000 Lbs. This kit promises to deliver a ride akin to torsion axles, but at a significantly lower cost, all while improving trailer handling. My previous trailer, while functional, suffered from noticeable “chucking” – that jarring fore-to-aft movement that can rattle both cargo and occupants. It was this persistent issue that prompted me to look for a robust suspension upgrade that could mitigate such unpleasant road feedback.
Upon unboxing, the initial impression was one of solid construction. The components felt substantial, a good indicator for something designed to withstand the rigors of the road. I had briefly considered other aftermarket equalizer systems, and even the more expensive torsion axle upgrades, but the specific engineering of the Equa-Flex system and its stated benefits for spring axles caught my attention. This specific Lippert kit felt like a well-engineered solution, offering a distinct advantage over basic rubber or U-bolt setups. My immediate feeling was one of cautious optimism, a strong hint that this upgrade might finally solve my trailer’s ride quality issues.
Real-World Testing: Putting Lippert 279689 Heavy Duty Equa Flex Rubberized Equalizer Triple Axle Kit 5 000 To 8 000 Lbs. to the Test
First Use Experience
I tested this triple axle kit on my gooseneck trailer, specifically focusing on its performance during highway driving, navigating uneven rural roads, and even during initial loading and unloading procedures. The installation process itself, while requiring some mechanical aptitude and the right tools, was straightforward once I understood the orientation of each component. The rubberized elements of the equalizer were noticeable from the outset, providing a subtle but definite dampening effect.
During the first hundred miles, the reduction in road shock was immediately apparent. Potholes and expansion joints that previously sent sharp jolts through the trailer chassis now felt considerably softer. The notorious “chucking” I had experienced was dramatically reduced, leading to a much more comfortable and controlled towing experience. The kit performed admirably even when the trailer was fully loaded with heavy equipment, maintaining its smooth ride characteristics.
Extended Use & Reliability
After several months and well over a thousand miles of varied terrain, the Lippert Equa-Flex system continues to impress. The rubberized components show no signs of premature cracking or stiffness, even after enduring several days of significant rain and fluctuating temperatures. Maintenance has been minimal; a quick visual inspection for any debris trapped in the rubber and ensuring all mounting bolts remain secure is all that’s needed.
Compared to the previous leaf spring setup, the difference is night and day. The trailer feels more planted, and the constant vibration that used to fatigue the truck and occupants has been significantly lessened. There have been no instances of unexpected performance drops or component failures, reinforcing the perception of a durable and reliable suspension enhancement. This kit has certainly proven its worth in terms of long-term usability and robust performance.
Breaking Down the Features of Lippert 279689 Heavy Duty Equa Flex Rubberized Equalizer Triple Axle Kit 5 000 To 8 000 Lbs.
Specifications
The Lippert 279689 Heavy Duty Equa Flex Rubberized Equalizer Triple Axle Kit 5 000 To 8 000 Lbs. is engineered to support tandem or triple axle trailers with individual axle capacities ranging from 5,000 to 8,000 lbs. This means the kit is designed for trailers with a total gross vehicle weight rating (GVWR) that falls within this robust range, making it suitable for many heavy-duty applications. The core of the system relies on rubberized equalizer subunits which are crucial for absorbing shock and vibration. These subunits are constructed from a resin-reinforced material to ensure longevity and resistance to cracking.
The kit includes two of these specialized equalizer subunits, along with two corresponding upper weldmounts that integrate with the trailer frame. Importantly, each subunit comes with pre-installed bronze bushings, which provide a smooth pivot point and reduce friction during suspension movement. This attention to detail in componentry is key to the system’s effectiveness.
Performance & Functionality
The primary function of this Lippert equalizer kit is to significantly dampen fore-to-aft trailer movement, commonly known as “chucking.” It achieves this remarkably well by allowing each axle to articulate independently to a degree, while the rubberized element absorbs the energy that would otherwise be transmitted directly through the trailer frame. This results in a ride that genuinely approaches the smoothness of torsion axles, a significant improvement over standard spring-leaf setups.
The main strength of this system lies in its ability to dramatically reduce trailer and cargo damage caused by road shock and vibration. While it excels at this, it’s important to note that it doesn’t eliminate all trailer bounce, as that can be influenced by other factors like tire pressure and load distribution. Nevertheless, the improvement in overall ride quality and stability is undeniable and directly meets, if not exceeds, expectations for this type of upgrade.
Design & Ergonomics
The design of the Lippert 279689 Heavy Duty Equa Flex Rubberized Equalizer Triple Axle Kit 5 000 To 8 000 Lbs. is functional and robust. The use of resin-reinforced rubber for the equalizer subunits suggests a material chosen for both its shock-absorbing properties and its durability under stress. The bronze bushings are a good choice for wear resistance and smooth operation.
While the components themselves don’t have intricate ergonomic features in the traditional sense, their integration into the trailer’s suspension is designed for ease of installation and straightforward operation. The upper weldmounts are designed to be securely attached to the trailer frame, and the equalizer subunits connect the axles, creating a unified yet flexible suspension system. The overall feel is one of sturdy, no-nonsense engineering focused on performance and longevity.
Durability & Maintenance
Based on my extended testing, this triple axle kit appears to be built for the long haul. The resin-reinforced construction of the equalizer subunits is a testament to Lippert’s commitment to durability, aiming to prevent the common issues of cracking or material degradation seen in lesser components. The pre-installed bronze bushings are designed for smooth, low-friction movement, which contributes to reduced wear over time.
Maintenance is refreshingly simple. Aside from regular checks for loose hardware, there are no complex lubrication or adjustment requirements. This makes it an ideal upgrade for users who want a reliable suspension solution without a significant ongoing maintenance burden. Potential failure points are minimal, primarily revolving around ensuring proper installation and avoiding over-stressing the system beyond its 5,000 to 8,000 lbs per axle rating.
Accessories and Customization Options
The Lippert Equa-Flex kit is designed as a direct replacement or upgrade for existing equalizer systems, so it primarily focuses on the core components needed for the suspension enhancement. It includes the two Equa-Flex sub units and two upper weldmounts, along with their respective pre-installed bronze bushings.
The description notes that the center hanger and other mounting hardware are sold separately. This is a crucial detail for potential buyers to be aware of, as these essential pieces will need to be sourced to complete the installation. While there are no inherent “customization” options for the rubberized equalizer itself, the true customization comes from selecting the correct kit for your trailer’s axle weight rating.
