The Kyosho UM579 Front Shock Stay was designed for the Ultima SB to provide firm support and consistent suspension geometry. It helps the car maintain predictable handling across mixed surfaces.
By adding rigidity where the front shocks mount, the Kyosho UM579 reduces unwanted movement and helps keep steering inputs accurate during aggressive driving.
This front shock stay mates to the Ultima SB chassis with correct alignment, so you can fit it without cutting or reworking the chassis layout.
