The Yokomo B7-S3NA Aluminum Normal Spring Cup is a key upgrade for racers running the BD7-2014 chassis. Machined from quality aluminum, these cups give stronger support and better longevity for your shock assembly. Supplied as a pair, they suit drivers focused on fine tuning and consistent lap times.
Aluminum cups resist deformation better than plastic, helping the suspension keep its setup under hard use. That stability reduces unpredictable handling and gives a firmer, repeatable feel when cornering or hitting bumps.
Made to match the BD7-2014 standard shock layout, these cups install without modification and slot into the original shock towers. That straightforward fit makes them a practical upgrade for racers and weekend builders alike.
