Let’s Dive into Progress MFG 90-02-4100 Equal I Zer 2″ Adjustable Shank 3″ Drop 7″ Rise 12in Length
The Progress MFG 90-02-4100 Equal I Zer 2″ Adjustable Shank 3″ Drop 7″ Rise 12in Length might not be the sexiest piece of gear, but it’s arguably one of the most critical for safe and comfortable towing. Manufactured by Progress MFG, this adjustable shank is the unsung hero ensuring your trailer tows level, preventing sway and potentially disastrous situations on the road. With a 2″ shank, adjustable drop of 3″ and rise of 7″ over a 12″ length, this shank promises versatility. It’s designed to fit a range of towing setups, a promise I was eager to verify.
My need arose when I upgraded my camping trailer. The new trailer sat considerably higher than my old one, causing a noticeable and unsettling sag in the tow vehicle’s rear. This affected handling and fuel economy, and made me constantly worried about stability. I considered a few options, but the adjustability of the Progress MFG shank, and the reputable name behind it, swayed my decision.
Unboxing the Progress MFG 90-02-4100 Equal I Zer 2″ Adjustable Shank 3″ Drop 7″ Rise 12in Length, the first thing I noticed was its robust construction. The weight suggested solid steel, and the finish looked durable, promising resistance against rust and corrosion. Build quality appeared excellent, inspiring confidence that this was a part built to last, not just something to get me by.
I considered a fixed-height shank from Curt and an adjustable ball mount from Andersen Hitches. I chose the Progress MFG due to its simplicity and the specific drop/rise range it offered. Plus, the Equal-i-zer name, associated with weight distribution hitches, gave me faith in its engineering. My initial impression was one of cautious optimism. I hoped it would solve my towing woes, and so far, it certainly looked the part.
Real-World Testing: Putting Progress MFG 90-02-4100 Equal I Zer 2″ Adjustable Shank 3″ Drop 7″ Rise 12in Length to the Test
First Use Experience
My first test run involved towing my travel trailer from my home in Colorado Springs to Pueblo Reservoir State Park. This route includes a mix of highway driving and some winding mountain roads. The Progress MFG 90-02-4100 Equal I Zer 2″ Adjustable Shank 3″ Drop 7″ Rise 12in Length was relatively easy to install, sliding smoothly into my receiver hitch.
I experienced both sunny and slightly windy conditions during this initial tow. The shank did its job admirably, keeping the trailer level and significantly reducing sway, especially on the highway. It took some minor adjustments to get the perfect height, but the adjustability was a breeze to use. Post adjustment, the ride was far smoother than before.
I needed a wrench to tighten the bolts initially, and I fiddled with the setup for about 30 minutes. I’m calling that easy, though, compared to the alternative of a dangerous tow. There were no immediate issues, and the initial result was a much more controlled and stable towing experience.
Extended Use & Reliability
After several months and thousands of miles towing with the Progress MFG 90-02-4100 Equal I Zer 2″ Adjustable Shank 3″ Drop 7″ Rise 12in Length, I can confidently say it’s holding up well. I have used it on multiple camping trips and even a cross-state move. There are no signs of bending or cracking.
The finish shows some minor scratches from road debris, but no rust has appeared. I regularly clean the shank with a wire brush and apply a coat of grease to the hitch ball. This simple maintenance has kept it in excellent working condition.
Previously, I had a fixed-height shank that required constant adjustments using blocks, which were unsafe and cumbersome. This Progress MFG adjustable shank far outperforms that setup in terms of convenience, safety, and overall towing comfort. It is a worthy upgrade.
