Key Features
- Precision Manufactured Design — Each crush tube is manufactured to exacting standards to ensure an accurate fit to the motor shaft of your RC vehicle, eliminating any inconsistencies or tolerance issues that could compromise performance or cause fitment problems.
- 5mm Motor Shaft Compatibility — These crush tubes are specifically engineered to be used on motor shafts with a 5mm diameter, making them compatible with a wide range of ARRMA brushless RC models including the Felony, Infraction, TALION, and Typhon ranges.
- Drivetrain Protection — The crush tube prevents the pinion gear from moving towards the motor if the set screw comes loose, which is a common issue that can lead to grinding noises, reduced power transmission, and potential drivetrain damage during high-speed running or competition.
- Steel Construction for Long-Term Durability — Manufactured from steel rather than cheaper aluminium alternatives, these crush tubes are built to withstand repeated impacts, vibrations, and the stresses of aggressive RC driving without deforming or failing prematurely.
- Exact Dimension Specifications — With an internal diameter of 5mm, external diameter of 7mm, and length of 5mm, these crush tubes match OEM specifications precisely, ensuring perfect fitment and function within your RC vehicle's drivetrain.
- Pack of Two for Value — This pack includes two crush tubes, allowing you to maintain spare parts for your current vehicle or providing compatibility parts for multiple RC cars in your collection.
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.
