Track-Focused Caster Block Upgrade

The Tamiya 54063 - TRF501X Aluminum Caster Block is designed to improve handling and longevity on the race circuit. Built for the TRF501X chassis, this aluminum unit increases the caster to 12 degrees compared with the earlier 10-degree option and adds three extra upper arm settings to broaden setup choices without compromising strength.

Specifications

Material: Aluminum
Angle: 12 degrees
Compatibility: TRF501X chassis
Adjustability: 3 additional upper arm settings

A practical upgrade for hobbyists and competitors who want a more stable turn-in and refined steering response under race conditions.

How does changing from 10 degrees to 12 degrees affect cornering?

Moving to a 12-degree caster typically increases stability through mid and high speed corners and can make steering feel more direct. Expect differences in front-end grip and adjust with toe or shock settings accordingly.

Will this fit other Tamiya models?

This part is made specifically for the TRF501X chassis. It may not bolt into other models without modification, so check mounting points before attempting installation.

What tuning choices do the extra upper arm positions give me?

The three added upper arm positions let you tweak roll center and steering response. Try small steps when changing positions and record lap times to find the best balance for your setup.
