Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length Review

Does the Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length Live Up to Its Name?

For anyone who has ever wrestled with an imbalanced trailer setup, the concept of “equalizing” isn’t just a technical term; it’s a promise of stability and peace of mind. That’s precisely what drew me to the Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length. This particular shank is designed to integrate seamlessly with Progress MFG‘s Original Equalizer Sway Control Hitch systems, catering to a wide range of trailer weights from 6K to 14K. My specific need arose after a recent acquisition of a slightly heavier travel trailer, which, when coupled with my existing tow vehicle, created a noticeable tilt that felt anything but balanced. It became clear a simple receiver hitch wasn’t going to cut it for safe, comfortable towing.

My initial impression upon unboxing was one of solid, no-nonsense construction. The shank itself feels substantial, crafted from what appears to be robust steel, and the finish gives off an aura of durability. There’s a reassuring heft to it, suggesting it can handle the stresses of the road. I had briefly considered a more generic, fixed-drop shank, but the adjustability offered by this Progress MFG model seemed a more practical long-term solution, especially given the varying loadouts I sometimes employ. It promised to be a key component in achieving that coveted level of towing composure, and my immediate thought was one of cautious optimism – a feeling that this part might just be the missing piece to my towing puzzle.

Real-World Testing: Putting Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length to the Test

First Use Experience

My first real test drive with the Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length involved hooking up my 28-foot travel trailer for a weekend trip to a local state park. The installation was straightforward, requiring just a few turns of a wrench to secure it to my receiver hitch and then attaching the equalizer bars to the shank itself. I opted for a middle-ground setting initially, aiming for a relatively level trailer.

The immediate difference was palpable. As I pulled away from my driveway, the rear of my truck settled far less than before, and the trailer tracked much more predictably behind me. Throughout the 50-mile drive, which included some highway stretches and winding country roads, the usual subtle sway and truck squat were significantly reduced. The shank performed admirably, feeling like a single, cohesive unit with the hitch and trailer.

Extended Use & Reliability

After several months and over 2,000 miles of towing, the Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length has proven its mettle. I’ve towed in various conditions, from clear sunny days to persistent light rain, and even encountered some uneven rural roads. The shank has remained steadfast, with no discernible loosening or degradation in its performance.

Durability has been impressive; the powder coating has held up well against minor road debris, and there are no signs of rust or corrosion even after getting caught in a few downpours. Maintenance has been minimal, requiring only an occasional check of the bolts and a quick wipe-down. Compared to a previous, less robust hitch component I used years ago, this adjustable shank feels engineered for the long haul, offering consistent performance without any noticeable drop-off in its load-leveling capabilities.

Breaking Down the Features of Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length

Specifications

The core of this shank’s utility lies in its carefully designed specifications. It features a 2″ shank, the standard size for most modern receiver hitches, ensuring broad compatibility. The crucial adjustment comes from its 4″ drop and 8″ rise capabilities, allowing for precise leveling across a wide spectrum of tow vehicle and trailer combinations. This adjustability is facilitated by a multi-position pinhole system.

The 12-inch length of the shank provides ample clearance and adjustment range, preventing the trailer tongue from interfering with the tow vehicle’s bumper or tailgate. This shank is engineered to work specifically with Progress MFG‘s Original Equalizer Sway Control Hitch models designed for 6K, 10K, 12K, and 14K trailer weight capacities. The robust construction implies a significant load-bearing capacity, well beyond its stated compatibility limits, giving a sense of security.

Performance & Functionality

In its primary role, the Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length excels. It effectively distributes tongue weight and counteracts trailer sway, making for a significantly more stable and predictable towing experience. The shank’s ability to accommodate a considerable range of height differences between the hitch receiver and the trailer coupler is its standout functional aspect.

The main strength is its versatility; a single shank can adapt to different trailers or even different hitch heights on the tow vehicle without requiring multiple specialized parts. Its weakness, if one can call it that, is that it’s specifically tied to the Progress MFG Equalizer Sway Control Hitch system. While this ensures perfect integration, it limits its use to owners of that particular brand of hitch. Overall, it not only meets but often exceeds expectations for its intended purpose, particularly for those with varying towing needs.

Design & Ergonomics

The design of this adjustable shank is fundamentally practical and focused on function. The all-steel construction with a durable powder coat finish speaks to its intended use in demanding environments, offering a visually solid and robust appearance. The clean lines and precise manufacturing are evident in how the holes align perfectly with the hitch pins.

Ergonomically, once installed, it’s invisible in its operation, which is the highest compliment for a component like this. The ease of adjusting the drop or rise by simply removing and reinserting the hitch pin is straightforward, though ensuring the pin is fully seated and secured with its clip is crucial for safety. The 2″ receiver compatibility means it fits standard hitch setups without fuss.

Durability & Maintenance

From my experience, the Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length is built for longevity. Its heavy-duty steel construction and protective powder coating suggest it can withstand years of regular use, exposure to the elements, and the vibrations inherent to towing. I haven’t observed any cracks, significant scuffing, or signs of structural compromise, even after carrying heavy loads.

Maintenance is refreshingly simple: a quick rinse with water to remove mud or salt and occasional lubrication of the pinholes if they become stiff with use. The design avoids any complex mechanisms that could fail. The primary concern for longevity would be ensuring the pinholes don’t wear excessively from frequent adjustments, but with proper pin insertion and removal, this seems unlikely.

Accessories and Customization Options

The Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length is part of a system, and as such, its “accessories” are primarily the components of the Progress MFG Equalizer Sway Control Hitch itself. This includes the stout hitch ball and the distinctive spring arms that provide the sway control and weight distribution.

While the shank itself doesn’t have further customization options beyond its adjustable height positions, its 2″ shank diameter means it is compatible with standard 2″ trailer hitches. This allows for integration with a wide variety of tow vehicles. The key “customization” is achieved through the selection of the correct Progress MFG hitch head and spring bars to match your specific trailer’s Gross Vehicle Weight Rating (GVWR).

Pros and Cons of Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length

Who Should Buy Progress MFG Equal I Zer 2″ Adjustable Shank 4″ Drop 8″ Rise 12in Length?

This adjustable shank is an ideal purchase for anyone who owns or plans to purchase a Progress MFG Equalizer Sway Control Hitch and needs to precisely level their trailer. It’s particularly suited for RV owners, horse trailer users, or anyone hauling equipment on a regular basis who encounters varying trailer tongue heights relative to their tow vehicle’s receiver. If you have a trailer that sits noticeably high or low on your hitch, this shank will be a game-changer for achieving a balanced setup.

Those who should probably skip this product are individuals using a different brand of weight-distribution or sway-control hitch, as it won’t integrate properly. It’s also not for someone who only occasionally tows a light utility trailer and doesn’t require advanced weight distribution or sway control. For maximum benefit, it’s recommended to pair this shank with appropriately rated Progress MFG spring bars and a hitch head that matches your trailer’s GVWR.

Conclusion on Progress MFG Equal I Zer 2″ Drop 8″ Rise 12in Length
