For hobbyists focused on consistent lap times, the Yokomo ZB-009R Rear Trailing Arm Pins are a reliable upgrade for the YZ-834B Dog Fighter. These pins are specified for the YZ-834B chassis to give firmer rear control under load.
The ZB-009R pins are produced to tight tolerances so the trailing arm location remains repeatable from run to run. Durable materials cut down on wear, keeping handling predictable between rebuilds.
These pins fit the YZ-834B mounting points and can be installed with common hand tools. The straightforward swap makes it easy to upgrade or replace worn components trackside.
