Discontinued balance shoe
Hello,
We believe that the 15-177 will work as a replacement for the discontinued 15-175 since it uses the same S152 coil springs. The main difference is that the coil attaches inside of the slot of the 15-177, instead of on the outside of the 15-175 shoe.
Since this part was just discontinued in the last week, we haven't had the opportunity to try it ourselves and none of our customers have reported back on if it worked for them. If you decide to give it a try, please let us know how it goes. If you run into any problems, you can find our return policy here, though we see no reason why this couldn't work as a replacement.
Thank you for getting back to us with the good news! We will continue to recommend this replacement to other customers in the same position. Please let us know if you need anything else.
