Latest from MIP:

MIP introduces the ultimate top shaft for the AE vehicle line, the MIP 17.5 Eco All-in-1 Topshaft! Why is it called “All-in-1”? Well because it works with the original 3-gear rear motor, 4-gear mid motor, 4-gear V2 mid motor, 3 gear mid motor, and the MIP Box! How is this possible you may ask, well with a little bit of creativity and some awesome engineering we were able to fit the necessary bearing sizes on one top shaft. Along with the 5-in-1 capability the contact surface is 30% narrower than normal, equating to less overall drag/contact patch on the idler gear. If that isn’t enough, the All-in-1 Topshaft is the lightest on the market today coming in at a feather light 3.8 grams! So to reiterate, you get a top shaft that will work with any one of the transmissions on the market, a Topshaft that has less contact area meaning less overall drag, and a Topshaft that has less rotating mass than anything on the market today. Time to get what your 17.5 stock car needs; an MIP 17.5 Eco All-in-1 Topshaft!!!
