Front one-way differential for M18 allows you to fine-tune the handling characteristics of this already great-handling micro racecar. Allows for quicker steering but decreases braking performance, since only the rear wheels will brake. The one-way differential features high-quality one-way bearings, CNC machined diff body (blue), and high-strength lightweight CNC-machined outdrives made from HUDY Spring Steel™ (available separately)

For use only at the front of the M18, not the rear.
