Technical Performance
These extreme heavy-duty caster blocks represent Traxxas' engineering commitment to suspension performance and durability. The caster geometry is critical to RC vehicle handling, affecting steering response, stability during acceleration and braking, and overall cornering performance. By upgrading to extreme heavy-duty c-hubs, you benefit from superior material density and structural reinforcement that prevents flexing under load. The 3x26mm hinge pins provide robust pivot points that maintain consistent caster angles even when subjected to the high impacts and stresses typical of competitive racing or aggressive bashing sessions. The inclusion of 3x15mm ball cup screws ensures proper articulation of the suspension while resisting loosening from vibration. These components work together to deliver the geometry and reliability that Traxxas is renowned for throughout the RC community. Whether you're running a brushless RC stadium truck at high speeds or a ready to run RC vehicle over rough terrain, these caster blocks maintain their integrity and performance characteristics throughout extended use. The black finish provides excellent durability and aesthetic appeal whilst resisting corrosion.
