Improve the handling of your EB410 or ET410 series vehicles with these new Adjustable Ackermann Spindles. When used with the TKR6669A-D spindle arms, additional Ackermann positions are available that boost low-speed steering and provide a more direct and linear feel throughout the wheel travel. These new spindles allow less overall Ackermann than is possible by moving the steering link on the bellcranks. They are a direct replacement for TKR6553 and are compatible with all stub axles, universals, and spindle carriers for the EB410 and ET410 vehicles. Spindle Arms and M3x10 screws are not included.
