Yokomo ZM-414 Kingpin Set (4pcs.) — Off-Road Kingpin Replacement  [ZM-414]

Kingpin set for off-road suspension

The Yokomo ZM-414 Kingpin Set is an RC-scale replacement kit supplied as a 4 pcs set intended for off-road suspension maintenance. This write-up focuses on practical use, fitment considerations, and the role these kingpins play in keeping a buggy or short-course truck’s suspension functioning as expected.

Designed as service parts, these kingpins replace worn pivot points in the suspension assembly. They restore proper steering geometry and suspension articulation when original pins show play or wear, and are intended for routine workshop maintenance rather than performance upgrades.

Installation is straightforward for hobbyists familiar with hub disassembly: remove the wheel and hub carrier, extract the worn pin, fit the replacement ZM-414 kingpin, and verify free rotation of the hub and correct shims or spacers. Check for correct thread engagement and any retained clips or pins required by your hub design.

From a tuning perspective, replacing worn kingpins removes unwanted slop that can mask suspension setup changes. When changing these pins, re-check toe, camber, and steering free play to ensure the chassis behaves consistently after reassembly.
