Frequently Asked Questions

• Is the Team Associated TC7.2 Spur Gear Pulley and Diff X-Pin suitable for beginners? — This is a replacement component designed for users who already own a TC7.2 touring car platform. It is not a complete vehicle or beginner-level product, but rather a maintenance and repair part for established TC7.2 owners.
