M4-2.0 Selectorized Weight Stack Upgrade Kit - 260 lb

I really like the add-on weight stack kit. Before ordering it, I checked my Amazon order history, which indicated that I had originally purchased the M4-2.0. Unfortunately, that turned out not to be the case—I actually have the M4-1.0. To make the kit work, I had to drill out the plastic weight stack guides so they would fit the M4-1.0 guide tubes. I also had to purchase pulleys and adapt them to the weight stack rods, and I ended up reusing the original cables. Despite the additional modifications, I was able to get everything working properly. The company provided a $100 credit toward my order, which I appreciated and helped offset the extra effort and parts required. At the end of the day, I was able to make the kit work and am happy with the final result.
