The Tamiya 54543 Aluminum Cup Joints present a practical replacement for the stock parts on TB04 and TB04 PRO touring chassis. They are engineered for correct fit and improved service life.
Fitting the aluminium cup joints reduces rotating mass by about 6.6 grams. The anodised finish lowers friction, while the included pin protectors help prevent premature wear on the joint and driveshaft interfaces.
These cups are compatible with TB04 and TB04 PRO models and are a sensible upgrade for racers and hobbyists who want dependable, low-maintenance driveline parts.
