It looks like you need a new coil balance and shoe. I recommend our 3/8" thick Series 165 coil and 15-199 pivot shoe. Look these parts over and let me know what you think.

You'll need the stamp printed on the old coil to confirm that. If you don't have a stamp, or if you can't find it, then tell me the exact weight of the sash. Please also tell me how many springs are on each side of the window. I can use a little math to figure it out.

Thanks! If the sash is 6 pounds, and you only have one spring on each side, then you'd want two 3 pound springs. That'd be our S165-3.
