The Yokomo B7-S3NA Aluminium Normal Spring Cup is aimed at drivers wanting improved durability on the BD7-2014 chassis. Turned from aluminium for dependable wear resistance, these cups help maintain consistent spring seating and damping behaviour. Supplied as two pieces, they are useful for builders focused on setup accuracy.
Aluminium offers improved rigidity compared to plastic, cutting down on flex and wear during heavy use. The result is steadier handling and less frequent replacement, which helps maintain predictable chassis balance during practice and events.
These spring cups match the BD7-2014 standard shock arrangement, allowing direct installation without altering shock towers. That makes them a practical upgrade for racers and hobbyists seeking simple, effective improvements.
