Let’s Dive into Progress MFG 90-02-4725 Equal I Zer Shank 2.5″ 12in Drop / 15″ Rise x 12″
The Progress MFG 90-02-4725 Equal I Zer Shank 2.5″ 12in Drop / 15″ Rise x 12″ is a crucial component for anyone serious about towing, especially those using the Equal-i-zer Sway Control Hitch system. It provides the vital connection between your tow vehicle and the hitch head, allowing for adjustable height to maintain a level trailer. With its robust construction and versatile adjustability, this shank promises to be a reliable workhorse for your towing needs.
My journey to this shank began with a persistent problem: trailer sway. Towing a travel trailer with our family SUV was becoming increasingly stressful due to unpredictable road conditions and wind gusts. I needed a solution that would not only control sway but also allow me to fine-tune the hitch height for optimal towing performance.
Upon unboxing the Progress MFG shank, I was immediately impressed by its heft and solid construction. The black powder-coated finish looked durable, promising resistance to rust and corrosion. The welds appeared clean and robust, instilling confidence in its load-bearing capabilities.
Compared to a generic ball mount I had previously used, the Progress MFG shank felt significantly more substantial. I also considered a similar shank from Curt, but the Equal-i-zer system’s reputation for sway control swayed me towards Progress MFG. My initial impression was one of relief and anticipation; I was excited to see if this shank would finally tame the beast that was our swaying travel trailer.
