Let’s Dive into Progress MFG Equal I Zer 2″ Adjustable 4K Shank
The Progress MFG Equal I Zer 2″ Adjustable 4K Shank is a critical component for anyone using an Equal-i-zer sway control hitch. Designed for versatility and strength, this shank allows for fine-tuning the hitch height to match various tow vehicle and trailer combinations. It’s a crucial piece of equipment for safe and comfortable towing, especially when dealing with heavier loads where sway control is paramount.
I found myself needing the Progress MFG Equal I Zer 2″ Adjustable 4K Shank after upgrading to a larger travel trailer. The standard shank that came with my initial Equal-i-zer hitch wasn’t providing enough drop, causing the trailer to ride nose-high. This not only looked awkward but, more importantly, negatively impacted the trailer’s handling and braking performance.
The Progress MFG Equal I Zer 2″ Adjustable 4K Shank arrived well-packaged and upon unboxing, I was immediately impressed with the heft and solid construction. The welds looked clean and robust, and the powder coat finish appeared durable. My first thought was, “This thing is built to last!”
I considered the Curt Manufacturing Adjustable Shank and the Andersen Manufacturing No-Sway Weight Distribution Hitch Shank, but ultimately chose the Progress MFG Equal I Zer 2″ Adjustable 4K Shank due to its direct compatibility with my existing Equal-i-zer hitch. I also preferred the incremental adjustability offered by its design.
My first impression was a mixture of excitement and relief. I was excited to finally achieve a level trailer and improve handling. I was relieved to find a product that appeared so well-made and ready for the task at hand.
Real-World Testing: Putting Progress MFG Equal I Zer 2″ Adjustable 4K Shank to the Test
First Use Experience
My first real test was a weekend camping trip to the nearby mountains. I was towing my 24-foot travel trailer, weighing in at around 4,000 lbs. The Progress MFG Equal I Zer 2″ Adjustable 4K Shank allowed me to perfectly level the trailer, which immediately made a noticeable difference in the tow vehicle’s handling.
The trip involved some steep grades and winding roads. The improved weight distribution and sway control were immediately apparent. I felt much more confident and in control compared to my previous setup.
Installation was straightforward, although adjusting the height required some trial and error. The instructions were clear, and the hitch head mounting holes, spaced at 1-1/4″ on center, aligned perfectly.
There were no major issues, although I did notice some minor rattling from the hitch ball connection point. This was easily resolved with a tighter ball mount and anti-rattle shims.
Extended Use & Reliability
After several months of use, including multiple trips totaling over 3,000 miles, the Progress MFG Equal I Zer 2″ Adjustable 4K Shank has performed flawlessly. There are no signs of bending, cracking, or any other structural issues. The powder coat finish is still intact, with only minor cosmetic wear from road debris.
The Progress MFG Equal I Zer 2″ Adjustable 4K Shank requires minimal maintenance. I occasionally check the bolts for tightness and apply a light coat of grease to the adjustable surfaces to prevent corrosion. This simple routine has kept it in excellent working condition.
Compared to my previous fixed-height shank, the Progress MFG Equal I Zer 2″ Adjustable 4K Shank is a significant upgrade. The adjustability has proven invaluable. It has allowed me to fine-tune my towing setup for optimal performance and safety.
