The Tamiya 54543 Aluminum Cup Joints are a direct replacement designed for TB04 and TB04 PRO touring chassis. These aluminium cups give a solid upgrade path for drivers wanting tougher driveline components.
Swapping the stock cups saves about 6.6 grams of rotating weight. The anodised surface helps reduce friction, while the supplied pin protectors guard the drive shaft and joint cup from premature wear.
These cup joints are intended for use on TB04 and TB04 PRO models and provide a reliable, straightforward swap-in for weekend racers and club drivers looking for longer-lasting parts.
