Going All In on the Progress MFG Equal I Zer 2″ Adjustable Shank
Towing can be a balancing act, and achieving that perfect alignment between your tow vehicle and trailer is paramount for safety and a smooth ride. This is where the Progress MFG Equal I Zer 2″ Adjustable Shank comes into play, offering a vital piece of hardware designed to bring stability and control to your towing setup. It’s a component that addresses the often-overlooked complexities of hitch geometry, allowing for a more adaptable and secure connection.
My own journey to finding this particular shank was driven by a persistent annoyance: a slight but noticeable “push” from my trailer on windy days, even with a properly loaded rig. It wasn’t a dangerous situation, but it was enough to make me constantly vigilant and frankly, a little less relaxed on longer hauls. I needed something that could fine-tune the hitch’s attitude, something beyond just the standard drop or rise.
Upon unboxing the Progress MFG Equal I Zer 2″ Adjustable Shank, my first impression was one of solid, no-nonsense engineering. The steel felt substantial, with clean welds and a durable-looking finish that suggested it could withstand the elements and the rigors of regular towing. It felt like a piece of equipment built to do a job, not just look pretty. I had briefly considered a few other generic adjustable shanks, but their construction often felt lighter, lacking the specific design cues for sway control integration that this model promised. A sense of quiet satisfaction washed over me; this looked like a component that would indeed solve my alignment woes.
Real-World Testing: Putting Progress MFG Equal I Zer 2″ Adjustable Shank to the Test
First Use Experience
I installed this adjustable shank in my home garage, a space that sees its fair share of automotive and workshop tasks. The process was straightforward, involving the removal of my existing hitch shank and the insertion of this new, more versatile unit. It slid into the receiver hitch with a satisfyingly snug fit, ready to connect to my trailer’s weight distribution system.
The real test, however, came on a weekend trip to the mountains, a route known for its elevation changes and gusty crosswinds. In the first few miles, I immediately noticed a difference; the trailer felt more “connected” to the truck, less prone to those disconcerting side-to-side movements. Even on uneven road surfaces, the rig tracked straighter, and the constant need to make minor steering corrections was noticeably reduced.
The ease of adjustment was a standout feature. During a stop at a scenic overlook, I was able to fine-tune the shank’s angle within minutes, using basic hand tools to dial in the perfect levelness for my trailer. This flexibility meant I could adapt to slightly different loading scenarios or even subtle changes in tire pressure between the truck and trailer. There were no immediate issues or unexpected quirks; it performed precisely as advertised, offering immediate improvements in handling.
Extended Use & Reliability
Over several months and hundreds of miles of towing, the Progress MFG Equal I Zer 2″ Adjustable Shank has proven itself to be a reliable workhorse. It has endured everything from dry desert highways to damp coastal roads, and its performance has remained consistently strong. There have been no signs of significant wear and tear; the pivot points remain firm, the locking pins engage securely, and the finish is holding up remarkably well against road grime and the occasional splash of mud.
Maintenance has been minimal, mostly involving a quick wipe-down after particularly dirty trips and a light application of grease to the pivot points. This simplicity is a major plus, especially when you’re on the road and don’t want to spend time fussing over equipment. Compared to some older, simpler shanks I’ve used in the past, this adjustable model offers far superior control and comfort without demanding extra upkeep. It has certainly outperformed budget alternatives that often develop slop or corrosion quickly.
Breaking Down the Features of Progress MFG Equal I Zer 2″ Adjustable Shank
Specifications
The Progress MFG Equal I Zer 2″ Adjustable Shank is engineered for adaptability and robust performance. It features a 2-inch shank, designed to fit standard receiver hitches of both 2-inch and 2-1/2-inch sizes, offering broad compatibility. The core of its functionality lies in its adjustable drop/rise capability, allowing for precise leveling of various trailer heights.
This adjustability is achieved through a series of secure pinholes and a robust locking mechanism. The shank is constructed from heavy-duty steel, ensuring it can handle significant towing loads and resist the stresses of the road. Its design is specifically intended to work seamlessly with the original Equalizer’s sway control head, enhancing stability by evening out trailer weight.
The flexibility in alignment provided by this adjustable shank is crucial for accommodating a wide range of tow vehicle and trailer combinations. This means you’re not limited by a fixed shank position, allowing for a more optimized towing posture that can contribute to a smoother and safer driving experience. It’s this attention to detail in accommodating diverse setups that makes it a valuable addition for many RVers and trailer owners.
Performance & Functionality
The primary job of the Progress MFG Equal I Zer 2″ Adjustable Shank is to facilitate precise leveling of your trailer and to integrate with sway control systems. In this regard, it performs exceptionally well. The ability to fine-tune the hitch angle means that I can achieve a perfectly level trailer, which is essential for proper weight distribution and preventing trailer sway.
Its strength lies in its adaptability. Whether I’m towing a slightly different trailer or have adjusted the load in my current one, I can quickly adjust the shank to maintain optimal alignment. The main weakness, if it can be called that, is the reliance on precise adjustment for maximum benefit; if you don’t take the time to set it correctly, you won’t see the full advantages. It meets and often exceeds expectations for its intended purpose, especially when compared to fixed shanks that offer no room for adjustment.
Design & Ergonomics
The design of this adjustable shank is fundamentally practical and robust. The heavy-duty steel construction gives it a reassuringly solid feel, and the durable finish resists chipping and corrosion, even after exposure to harsh weather conditions. Its overall build quality speaks to its intended use in demanding towing environments.
Ergonomically, the shank is designed for functionality rather than comfort. The primary interaction is with the locking pins and adjustment holes, which are spaced appropriately to allow for fine-tuning. While it’s not something you interact with constantly, the ease with which these pins can be inserted and removed, along with the clear visual cues of the adjustment positions, makes it user-friendly. The main practical design detail is the clearly marked adjustment positions, which are easy to read and interpret, even when partially obscured by dirt or grime.
Durability & Maintenance
Given its solid steel construction and quality finish, the Progress MFG Equal I Zer 2″ Adjustable Shank is built for longevity under typical towing conditions. I anticipate it will last for many years, likely outliving several tow vehicles. Its simple design with minimal moving parts means there are few points of failure.
Maintenance is commendably straightforward. A basic cleaning after dusty or muddy excursions, followed by occasional lubrication of the pivot mechanism, is all that’s generally required. There are no complex components to disassemble or delicate parts to worry about. The primary concern for longevity would be ensuring the adjustment pinholes do not become excessively worn or damaged, which could compromise the security of the pin engagement.
Accessories and Customization Options
The Progress MFG Equal I Zer 2″ Adjustable Shank is primarily designed to integrate with existing sway control systems, specifically mentioning compatibility with the Original Equalizer’s sway control head. It doesn’t come with many additional accessories beyond the necessary adjustment pins and retaining clips, which are integral to its function.
However, its 2-inch receiver interface means it’s compatible with a vast array of aftermarket trailer balls, drop chains, and other hitch-mounted accessories, provided they use the standard 2-inch shank mount. This adaptability allows users to build a complete towing system around it. For those looking to enhance their sway control further, ensuring their chosen sway control head is compatible is the key, rather than accessories directly for the shank itself.
Pros and Cons of Progress MFG Equal I Zer 2″ Adjustable Shank

- Seamless integration with sway control heads like the Original Equalizer for enhanced stability.
- Easy adjustment mechanism using pins, allowing for quick and straightforward leveling.

Cons
- Can be a bit of an upfront investment compared to basic, non-adjustable shanks.

Who Should Buy Progress MFG Equal I Zer 2″ Adjustable Shank?
The Progress MFG Equal I Zer 2″ Adjustable Shank is ideally suited for RV owners, utility trailer users, or anyone who frequently tows trailers of varying heights or with different tow vehicles. It’s particularly beneficial for those experiencing minor issues with trailer leveling or seeking to optimize their trailer’s aerodynamics and stability, especially those already using or considering an integrated sway control system. This adjustable shank is a great choice for anyone who values precise alignment and a smoother towing experience, and who might switch trailers or vehicles with some frequency.
Individuals who only tow a single trailer with a fixed hitch height, or those who are not concerned with fine-tuning their trailer’s level attitude, might find the adjustable feature somewhat overkill. For those looking for the absolute simplest, most budget-friendly solution and who never anticipate needing to adjust hitch height, a standard fixed-drop shank could suffice. A good complementary item would be a reliable torque wrench to ensure all hitch connections are properly tightened for maximum safety.

The ability to precisely level a trailer, especially in conjunction with a sway control system, provides a tangible benefit on the road, reducing driver fatigue and increasing confidence.
