The Yokomo S4-201PA Aluminum Steering Bellcrank Post is a precision machined aluminium upgrade made for the YZ-4S chassis. Constructed from durable aluminium, this bellcrank post tightens steering response and improves control for competitive driving.
Designed to handle repeated use on the circuit, the aluminium S4-201PA is stronger and more wear resistant than stock plastic parts. The reduced flex gives a more direct steering feel and extends the service life of your steering assembly.
This S4-201PA fits several YZ-4S variants including B-YZ4SF, B-YZ4SF2-1, MOR-010, and MOR-020 chassis. Installation uses standard hardware and can be completed quickly between practice runs.
