Technical Performance
The ARRMA Crush Tube is engineered with meticulous attention to detail, featuring steel construction that provides superior durability compared to lighter materials. With an internal diameter of exactly 5mm and an external diameter of 7mm, these crush tubes maintain tight tolerances that ensure a secure fit on your motor shaft without any looseness or rocking. The 5mm length provides the optimal depth for holding your pinion gear securely in place. Steel construction is a critical engineering choice that prevents the crush tube from deforming under the combined forces of motor torque, pinion gear engagement, and the vibrations inherent to high-performance RC driving. Whether you're running a 6S brushless system in your ARRMA Felony 6S BLX, Infraction 6S BLX, TALION 6S EXB, or Typhon 6S V5 BLX, these crush tubes are engineered to handle the demands of brushless motor technology. The precision manufacturing process ensures that each crush tube meets exact specifications, eliminating the possibility of improper fitment that could lead to pinion gear movement and subsequent drivetrain noise or failure. For RC car enthusiasts in the UK who value reliability and want to protect their investment in high-performance brushless RC vehicles, the ARRMA Crush Tube represents essential maintenance and spare parts strategy.

Frequently Asked Questions
- What does a crush tube do on an RC car? — The crush tube is a small cylindrical component that slides onto your motor shaft and prevents your pinion gear from moving towards the motor if the set screw comes loose. This is especially important during high-speed running or aggressive driving where vibrations can loosen fasteners, potentially causing drivetrain damage and grinding noises if the pinion moves out of position.
- Which ARRMA models are compatible with the Z-ARA311026 crush tubes? — These crush tubes are designed for ARRMA vehicles featuring 5mm motor shafts, including the Felony 6S BLX in both Orange and Black variants, the Infraction 6S BLX in Silver and Blue, the TALION 6S EXB 4X4 RTR Speed Truck in Black, and the Typhon 6S V5 BLX. If you own any of these popular ARRMA brushless RC models, these crush tubes are the correct replacement parts.
- Why buy genuine ARRMA crush tubes instead of cheap alternatives? — Genuine ARRMA crush tubes are manufactured to precise specifications and constructed from durable steel, ensuring perfect fitment and long-term reliability. Cheaper alternatives may have loose tolerances, softer materials that deform under load, or incorrect dimensions that cause fitment problems. Investing in genuine OEM parts protects your more expensive RC vehicle and ensures consistent performance.
- How often should I replace crush tubes on my RC car? — Crush tubes are designed for long-term durability thanks to their steel construction, but they should be inspected regularly as part of your maintenance routine. Replace them if you notice deformation, rust, or any sign of wear. Most users find they need replacement only occasionally, making this an economical spare part to stock.
- Are these crush tubes suitable for beginners? — Yes, these crush tubes are essential spare parts for both beginners and experienced RC enthusiasts. If you're new to the hobby and own an ARRMA brushless RC car, having a spare set of crush tubes is good practice for basic maintenance and troubleshooting.
- Can I use these crush tubes on other brands of RC cars? — These crush tubes are specifically designed for ARRMA vehicles with 5mm motor shafts. If your RC car uses a different motor shaft diameter, these will not fit correctly. Always verify your vehicle's specifications before purchasing spare parts.
