I purchased the springs for my FasTrac for around $60. They aren't springs at all, simply iron bars that elevate the seat about 4" and give it a little bounce. They look like I made them. They have unprofessional cut-outs that look like they were retrofitted for another product. Once installed you don't see them. They don't pretend to be a true suspension seat like on the Super, which is extremely comfortable by the way. However, the more comfortable ride made me forget to slow down in some bumpy areas which caused an 'uneven' cut. Overall I like it, but would have been willing to pay more for true springs. I feel Hustler should provide this $10 part (if that) and add the cost to the mower. I also would of wanted the opportunity to purchase the Super Z suspension seat.
