JR Dragster No-Spin 7/16 Polar Post

We get this question daily..Why is this no-spin a big deal?Simple, when your child stages the Junior, the only means of the car creeping forward is via friction of the drive belt against the steel bushing. If the bushing is loose on the post, well guess what, no friction on the belt. Our post has a 7/16" threaded hole in the end of it, this can be used to assist in pushing the post off the crankshaft.Zero Error's exclusive replacement Billet Post with Steel Belt Bushing, our bushing will never spin. You will never buy another post due to your bushing spinning!
