First Use Experience
I first installed the Reese 66131 High Performance Trunnion Weight Distribution Kit 15000/1500 Lbs., Gtw/Tw on my receiver hitch in my garage. The kit is designed for trailers up to 15,000 lbs Gross Vehicle Weight (GTW) and 1,500 lbs Tongue Weight (TW), and I attached it to a sturdy bumper-pull travel trailer loaded for a weekend camping trip. The initial setup, while requiring careful reading of the instructions, felt manageable. The serrated washers on the head were indeed helpful for making precise adjustments, allowing me to dial in the stance of the trailer and tow vehicle for a more level ride.
My testing ground was a mix of local highways and some winding country roads leading to a popular state park. The conditions varied from smooth asphalt to sections with noticeable road imperfections and some gusty crosswinds. The true test came as I navigated through a steep mountain pass with sharp turns and significant elevation changes.
The ease of use was better than expected, particularly the snap-up brackets which made connecting the spring bars much less of a wrestling match than I’ve experienced with older systems. There was a slight learning curve in determining the exact number of links for the optimal chain tension, but the included nine-link chains offered ample range. I noticed an immediate improvement in trailer tracking and a significant reduction in chassis flex transmitted from the trailer to the truck.
Extended Use & Reliability
Over the course of several months and multiple trips, this weight distribution kit has proven its mettle. I’ve used it for everything from hauling a fully stocked cargo trailer to a weekend RV excursion, consistently loading the trailer near its Gross Vehicle Weight rating. Through this varied usage, the kit has maintained its performance without any noticeable degradation.
Durability has been impressive. Despite exposure to dust, road spray, and the occasional bump from maneuvering in tight spots, there are no signs of significant wear and tear. The spring bars retain their tension, the trunnion mounts operate smoothly, and the hitch head adjustment mechanism remains crisp and secure. There have been no leaks, cracks, or loose components, which speaks volumes about the robust construction.
Maintenance has been minimal. A quick wipe-down with a damp cloth after dusty drives and an occasional application of grease to the hitch ball is all that’s required. The design is straightforward, with no complex parts to clean or maintain. Compared to some of the lighter-duty, less robust systems I’ve used in the past, this Reese kit feels like it’s built for the long haul, offering a significant upgrade in reliability and peace of mind.
Breaking Down the Features of Reese 66131 High Performance Trunnion Weight Distribution Kit 15000/1500 Lbs., Gtw/Tw
Specifications
The Reese 66131 High Performance Trunnion Weight Distribution Kit 15000/1500 Lbs., Gtw/Tw is engineered with substantial capacity in mind. It boasts a Gross Trailer Weight (GTW) rating of up to 15,000 lbs and a Tongue Weight (TW) rating of up to 1,500 lbs. This significant capacity means it’s suitable for a wide range of larger travel trailers, fifth wheels (with appropriate adapter), and heavy-duty cargo trailers.
The kit features forged raised ball platform and trunnion mounts, which contribute to its strength and stability. The head design utilizes serrated washers for easier and more precise adjustments, a thoughtful touch that simplifies setup. Included are nine link chains, providing ample adjustment points for various trailer frame heights and types, and innovative snap-up brackets designed to ease the process of connecting the spring bars, especially on frames with larger profiles. The spring bars themselves are rated to be among the highest per class in the industry, ensuring effective weight distribution. This Reese kit is designed to work with a standard 2-inch receiver hitch, though the hitch bar itself is sold separately, a common practice in the industry.
These specifications translate directly into user experience. The high weight ratings offer a considerable safety margin for heavier loads, reducing the risk of trailer sway and improving vehicle handling. The robust construction materials, like forged steel, mean these components are built to endure considerable stress and vibration over time. The integrated design features, such as the snap-up brackets and serrated washers, are not just marketing points; they directly address common frustrations encountered during setup and adjustment of weight distribution hitches, making the process less physically demanding and more precise.
Performance & Functionality
In its core function, the Reese 66131 High Performance Trunnion Weight Distribution Kit 15000/1500 Lbs., Gtw/Tw performs exceptionally well. Its primary job is to redistribute the tongue weight of a trailer back to the trailer’s axles and the tow vehicle’s front axle, thereby leveling the vehicle-trailer combination and improving steering control and braking. This kit achieves that objective with remarkable effectiveness.
The key strength lies in the highest rated spring bars per class. These bars effectively dampen trailer oscillations and keep the tow vehicle and trailer in a stable, level alignment, even under challenging conditions. I experienced significantly reduced porpoising and sway during lane changes and when being passed by large trucks. The head design with superior strength and the forged raised ball platform contribute to a solid connection that inspires confidence.
A minor point for consideration, though not a true weakness, is that with extremely heavy trailers and precise tongue weight, fine-tuning the chain links can still require some physical effort. However, the inclusion of the snap-up brackets drastically mitigates this, making the process considerably easier than with systems lacking such features. Overall, the performance significantly exceeds the expectations set by its impressive specifications.
Design & Ergonomics
The design of this Reese weight distribution kit is focused on functionality and durability, which are paramount in this category. The use of heavy-gauge steel for all critical components, including the head assembly and spring bars, imparts a sense of ruggedness and longevity. The powder-coated finish provides a layer of protection against corrosion and minor abrasions, maintaining a professional appearance even after considerable use.
Ergonomically, the kit is designed to be managed with a reasonable amount of physical effort, especially thanks to the snap-up brackets. These brackets leverage the trailer’s tilt against the tow vehicle to help pull the spring bars into their mounting brackets, reducing the need for brute force. The serrated washers on the head assembly allow for precise angle adjustments with relatively simple tools, making it easy to achieve the desired trailer stance. While not a tool one uses constantly, the grip surfaces and the overall heft of the components feel secure and substantial during installation and adjustment.
The overall aesthetic is utilitarian, as expected for towing equipment, but the clean lines and robust construction give it a premium feel. The forged elements, like the raised ball platform, are not only strong but also visually indicate the quality of the manufacturing process. The design prioritizes ease of adjustment and secure engagement, which are critical for a safe and effective towing experience.
Durability & Maintenance
Based on my experience and the materials used, the Reese 66131 High Performance Trunnion Weight Distribution Kit 15000/1500 Lbs., Gtw/Tw is built for the long haul. The heavy-duty steel construction, combined with a quality powder coat finish, suggests it will withstand years of use in various weather conditions without significant degradation. The critical components, like the spring bars and trunnion pivots, are designed to handle immense stress, and there’s little indication they would fail under normal operating loads.
Maintenance is refreshingly simple. A periodic cleaning to remove road grime and debris is beneficial, especially around pivot points and the hitch ball. Applying a light coat of grease to the hitch ball (where it interfaces with the trailer coupler) is crucial for smooth operation and to prevent excessive wear. The spring bars themselves require no specific maintenance beyond ensuring they are securely attached. There are no complex mechanisms or sensitive parts that require special care.
Potential points of wear would primarily be on the hitch ball and within the trailer coupler due to friction. However, these are standard wear items for any hitch system and are easily replaceable if necessary. The kit itself, including the spring bars and the head assembly, appears exceptionally robust and unlikely to suffer from common failure modes like cracking or excessive bending under rated loads.
Accessories and Customization Options
The Reese 66131 High Performance Trunnion Weight Distribution Kit 15000/1500 Lbs., Gtw/Tw is a complete system for weight distribution, but it’s designed to integrate with your existing hitch setup. The kit includes the spring bars, trunnion brackets, snap-up brackets, and all necessary hardware for mounting to the trailer frame and connecting to the receiver hitch. As noted, the hitch bar, which slides into the tow vehicle’s receiver and holds the weight distribution head, is sold separately. This is common and allows users to select a hitch bar with the appropriate drop or rise and shank length for their specific tow vehicle.
The kit is also designed with future compatibility in mind, particularly for sway control. The product description mentions an optional Dual Cam High Performance Sway Control system, indicating that the head assembly is likely pre-drilled or designed to accommodate such an addition. This is a significant advantage, as it allows users to upgrade their setup later without replacing the entire weight distribution kit. While not included, this optional sway control is a highly recommended addition for anyone prioritizing maximum stability.
Beyond the optional sway control, the primary customization involves selecting the correct hitch bar and ensuring the trailer coupler is compatible with a standard 2-inch hitch ball, which is typically pre-installed on the weight distribution head. The kit itself is highly standardized and doesn’t typically require or offer further component customization for its core function.
