Let’s Dive into Progress MFG 90-02-4711 Equal I Zer Shank 12in Drop / 15″ Rise x 12″
The Progress MFG 90-02-4711 Equal I Zer Shank 12in Drop / 15″ Rise x 12″ might not be the sexiest piece of gear, but for anyone serious about towing, it’s a crucial component. This shank is designed to work with the Equal-i-zer weight distribution hitch system, and promises to provide the necessary adjustability to level out your trailer and tow vehicle.
For years I’ve wrestled with trailers that felt like they were steering the truck, especially in crosswinds. I needed a solution that would provide the proper drop or rise to ensure my trailer was level.
The package arrived in a sturdy cardboard box, well-protected from potential shipping damage. My initial impression was that this shank looks robust; the welds were clean and the powder coating seemed durable. It was heavier than I anticipated.
I considered a couple of adjustable ball mounts, but they didn’t offer the weight distribution benefits of the Equal-i-zer system. What stood out with this Progress MFG shank was its specific design for weight distribution hitches. I was optimistic about its ability to provide a stable towing experience.
I was mostly excited about the prospect of finally having a level and controlled towing experience. My first thought was, “This thing looks like it can handle anything I throw at it.”
Real-World Testing: Putting Progress MFG 90-02-4711 Equal I Zer Shank 12in Drop / 15″ Rise x 12″ to the Test
First Use Experience
I first put the Progress MFG 90-02-4711 Equal I Zer Shank 12in Drop / 15″ Rise x 12″ to the test on a weekend camping trip. I was towing my 24-foot travel trailer through the foothills of the Appalachians. The roads were a mix of smooth highway and winding, somewhat uneven back roads.
The weather cooperated initially, with clear skies, but a sudden downpour caught me halfway through the trip. Installation, while not exactly a breeze, was manageable with basic tools. The adjustability of the shank allowed me to dial in the perfect height for my trailer.
The most noticeable difference was the significant reduction in sway, especially when semi-trucks passed. I immediately appreciated the more controlled feel, especially on the winding back roads. There were no major issues, although tightening the bolts to the required torque took a little effort.
Extended Use & Reliability
After several months of regular use, the Progress MFG 90-02-4711 Equal I Zer Shank 12in Drop / 15″ Rise x 12″ has proven to be a reliable piece of equipment. I’ve towed my trailer over 5,000 miles in various conditions, from scorching summer heat to freezing winter temperatures.
There are a few minor scratches on the powder coating from road debris, but no signs of rust or structural damage. I make sure to clean the shank and grease the moving parts every few trips. So far, so good. It definitely outperforms the old ball mount I was using.
