Off-Road Kingpin Upgrade for Better Steering - Yokomo ZM-414 (4pcs)  [ZM-414]

Tuning benefits of new kingpins

The Yokomo ZM-414 Kingpin Set is a four-piece replacement kit made for off-road suspension service and setup work. This description focuses on how fresh kingpins help deliver consistent steering response during tuning sessions.

As maintenance parts, these kingpins remove play in pivot points so steering geometry remains predictable. They are intended to bring the chassis back to intended behaviour rather than act as a performance part.

To fit, disassemble the hub: remove wheel and hub carrier, withdraw the worn pin, install the ZM-414 replacement, then check hub rotation and shim placement. Ensure any retention clips or split pins are refitted correctly.

For setup work, eliminating kingpin slop helps the driver perceive changes to springs, shocks, and roll balance more clearly. After changing pins, confirm toe, camber, and steering free play to keep handling consistent.
