TB04 Driveline Upgrade with Tamiya 54543

The Tamiya 54543 Aluminum Cup Joints are a straightforward upgrade for TB04 touring car setups. Made for TB04 and TB04 PRO chassis, these cup joints improve durability while keeping fitment precise.

Weight and Wear Advantages

Swapping the stock cups for these aluminum units cuts rotating mass by about 6.6 grams. The anodized surface reduces friction and the included pin protectors help limit wear on both the drive shaft and joint cup.

Model Compatibility

These cup joints are specified for use on TB04 and TB04 PRO models, offering a direct replacement that suits racers and club drivers focused on longevity and smooth operation.

Will these fit a TB04 with aftermarket driveshafts?

They are designed for the stock TB04 and TB04 PRO geometry. If your aftermarket driveshafts keep the same dimensions, fit is likely, but double check shaft diameter and cup seating before installation.

What tools do I need to install the cup joints?

Standard RC hand tools are enough: small hex drivers, pliers, and a pin punch or thin driver for the roll pins. No specialty tools required.

How should I maintain the aluminum cups?

Keep the joints clean and periodically check the pin protectors for wear. A light, appropriate lubricant on mating surfaces helps keep friction low without attracting grit.
