Our window balance coil has broken into 2 pieces and we need to replace it. It has 6K stamped on it. Do you carry 6K or its equivalent?

Hello, thank you for writing in. You appear to have our 15-177 pivot shoe, which works with our Series 152 Coil Springs. Based on your stamp, you will need our S152-6.
