The Yokomo D-152-0 is a purpose-built narrow steering knuckle for RC suspension layouts. By shifting the kingpin axis toward the tread center while retaining track width, the block decreases scrub radius and creates a more balanced steering response. This allows sharper turning lines at larger steering angles without the tyre fouling the wheelarch, improving scale realism.
The part is intended to be used in conjunction with aluminium upper and lower A-arms. Proper installation on a DP chassis requires a special universal shaft and the specific arm adapters listed by the manufacturer. The D-152-0 employs a 0 degree kingpin; a 7 degree alternative is available as D-152-7.
If your build aims to refine steering geometry for sharper cornering and less tyre tuck, the D-152-0 is a compact upgrade; confirm adapter and shaft requirements before ordering.
