Progress MFG 90-02-4400 Equal I Zer Shank Review

Let’s Dive into Progress MFG 90-02-4400 Equal I Zer Shank

As someone who’s spent over a decade navigating the world of outdoor and tactical gear, I’ve seen my fair share of equipment failures – especially when it comes to towing. That’s why I was eager to get my hands on the Progress MFG 90-02-4400 Equal I Zer Shank, a crucial component for their popular weight distribution hitch system. It promised to provide a reliable and adjustable connection between my tow vehicle and trailer.

My old hitch shank was starting to show its age, exhibiting worrisome signs of rust and wear after years of hauling everything from camping trailers to utility trailers. I needed something robust and adjustable to handle various trailer configurations. The Equal-i-zer system’s reputation for sway control and weight distribution, coupled with Progress MFG’s known quality, made the 90-02-4400 shank an appealing upgrade.

Upon unboxing, my initial impression was positive. The shank felt solid and substantial, constructed from what appeared to be heavy-duty steel with a durable-looking finish. It definitely looked like it could withstand the rigors of frequent towing.

Compared to other shanks I’ve used, like the Curt Manufacturing adjustable shank and the Reese Towpower shank, the Progress MFG offered a wider range of adjustability and seemed more robustly built. I chose it primarily for its compatibility with the Equal-i-zer system and its reputation for reliable sway control. My first thought was, “This thing looks like it’s built to last.” I was excited to see if it lived up to its promises on the road.

Real-World Testing: Putting Progress MFG 90-02-4400 Equal I Zer Shank to the Test

First Use Experience

My first test run with the Progress MFG 90-02-4400 Equal I Zer Shank was a weekend camping trip to the mountains. I was towing my 24-foot travel trailer, a notoriously unstable load, known for swaying in crosswinds. Installation was straightforward, aligning perfectly with my existing Equal-i-zer hitch head.

The weather was typical mountain fare: sunny skies turning into gusty winds and a brief rain shower. Even with the unpredictable conditions, the shank, coupled with the Equal-i-zer hitch, provided a noticeably more stable towing experience. The trailer felt securely connected and much less susceptible to sway compared to my previous setup. No adjustments were needed during the trip.

Extended Use & Reliability

After several months of regular use, including multiple long-distance trips and local hauls, the Progress MFG 90-02-4400 Equal I Zer Shank has proven its worth. It continues to perform flawlessly, maintaining its stability and adjustability. There are no signs of bending, cracking, or excessive wear, even after being subjected to rough roads and heavy loads.

Maintaining the shank is simple: I give it a quick cleaning after each trip to remove dirt and grime, and I occasionally apply a rust preventative spray to protect the finish. The Progress MFG shank requires minimal maintenance. In comparison to my previous, cheaper shank, the difference in performance and peace of mind is substantial.

Breaking Down the Features of Progress MFG 90-02-4400 Equal I Zer Shank

Specifications

• Designed for use with Progress MFG Equal-i-zer sway control hitches: Specifically, the 6K, 10K, 12K, and 14K no-shank models. This ensures seamless integration and optimal performance of the entire system.

• Fits standard 2″ or 2-1/2″ receiver tubes: Providing versatility and compatibility with a wide range of tow vehicles. Many newer trucks come with 2.5″ receivers for heavier towing, making this a crucial feature.

• Hitch head mounting holes spaced at 1 1/4″ on center: Ensures a secure and precise fit with the Equal-i-zer hitch head. This precise spacing guarantees proper weight distribution and sway control.

• Sway Control and Weight Distribution: This shank is an integral part of the Equal-i-zer system. Together they provide superior sway control and weight distribution for safer towing.

Performance & Functionality

The Progress MFG 90-02-4400 Equal I Zer Shank excels at providing a stable and adjustable connection for weight distribution and sway control. It effectively transfers weight from the rear of the tow vehicle to the front axle and the trailer axles, leveling the load and improving handling. The result is reduced sway, improved steering, and increased braking performance.

The shank’s adjustability is a major strength, allowing you to fine-tune the hitch height to match different trailers and load configurations. A potential weakness is the weight of the shank itself, but it is necessary for strength and stability. It definitely meets expectations, providing a noticeable improvement in towing safety and comfort.

Design & Ergonomics

The Progress MFG 90-02-4400 Equal I Zer Shank boasts a simple but effective design. The heavy-duty steel construction inspires confidence, while the adjustable height settings are easy to use and secure. While not particularly ergonomic in the traditional sense, its functionality contributes to a more comfortable and less stressful towing experience.

There’s no real learning curve involved. If you’re familiar with weight distribution hitches, you will find the shank easy to install and adjust.

Durability & Maintenance

Given its robust construction, the Progress MFG 90-02-4400 Equal I Zer Shank is built to last. With proper care and maintenance, it should provide years of reliable service. Regular cleaning and rust prevention are all that’s needed.

Repairs are unlikely, but replacement parts are readily available from Progress MFG and their distributors. This ensures long-term usability and protects your investment.

Accessories and Customization Options

The shank itself doesn’t offer many customization options, as it’s a core component designed to work specifically with the Equal-i-zer system. However, you can adjust the height to achieve the optimal towing angle. It is compatible with various ball mounts depending on your trailer’s coupler size.

You can also use different sized hitch balls to accommodate varying trailer coupler sizes. It’s important to note that this shank is designed only for use with the Equal-i-zer hitch head and should not be used with other weight distribution systems.

Pros and Cons of Progress MFG 90-02-4400 Equal I Zer Shank

Who Should Buy Progress MFG 90-02-4400 Equal I Zer Shank?

This shank is perfect for anyone who frequently tows trailers, especially travel trailers or other large loads prone to sway. It is also ideal for RVers, contractors, and anyone who values safety and stability while towing. If you already own an Equal-i-zer hitch head (6K, 10K, 12K, or 14K no-shank models), this is a must-have upgrade.

If you only occasionally tow small, lightweight trailers, a basic ball mount might suffice. Also, if you don’t own an Equal-i-zer hitch head, this shank will be useless. A must-have accessory is a torque wrench to ensure proper tightening of the bolts during installation.
