Broken coil balance

A quick learner from Ann Arbor says:
Hi!
I need your help desperately!

Windows do not stay open and they are dropping. I think I need to replace the coil balance and shoe and I am wondering if S140-25 is a good fit.

Please let me know how you think!

Best,
Hyesun

Hello, Hyesun. No, I don't think our Series 140 will work for you. You have an entirely different setup. Your balance cover looks fine and you pivot shoe looks fine, so you may just need to replace broken coil springs. I believe a match is our Series 160 spring. To determine the proper option, refer to the stamp printed on your current springs.
