Need a new window balancer for milgard vinyl windows

Question

My balancer broke and I need a new one for one of my windows. Guessing it would make the most sense to replace both. The broken one is the left side if looking at the window from the inside.

Thanks for your photos. Based on what I see here, you have either our S380-27 or S385-27, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
