Technical Performance
The Traxxas Output shaft spacer TRX4994 is a precision-engineered component that plays a vital role in maintaining the integrity of your RC vehicle's transmission system. Manufactured from high-quality materials using Traxxas' advanced production techniques, this 5x8x14mm spacer ensures that output shaft bearings maintain correct spacing and alignment. Proper spacing is absolutely critical in RC transmissions because even small deviations can lead to increased friction, heat generation, and accelerated wear of bearing races and seals. The spacer works in conjunction with other drivetrain components to manage radial and axial loads, distributing stress evenly across bearing surfaces. By maintaining precise geometry within the transmission case, this spacer enables smooth, efficient power transfer from the motor through the gearbox to the wheels. Whether you're running a high-performance brushless RC car UK model with aggressive driving dynamics or a more casual ready to run RC vehicle, this component ensures your drivetrain operates at peak efficiency. The dimensions have been calculated to work seamlessly with compatible Traxxas transmissions, and genuine factory parts like this ensure you're not introducing variables that could compromise performance or longevity. For serious RC hobbyists who understand that reliability comes from using correct components, the TRX4994 is an investment in peace of mind.

Frequently Asked Questions
- What Traxxas models use this TRX4994 output shaft spacer? — The TRX4994 is compatible with specific Traxxas models that use this particular transmission configuration. To confirm compatibility with your specific RC car, we recommend checking your vehicle's parts diagram or contacting our experienced team at RC Model Shop, who can verify fitment before you purchase.
- Why would I need to replace my output shaft spacer? — Output shaft spacers can wear over extended use, become damaged from impacts, or require replacement during routine transmission servicing and maintenance. If you notice transmission noise, rough shifting, or signs of wear in your drivetrain, a spacer may need replacement to restore smooth operation and prevent further damage to bearings and gearbox components.
- Is this a genuine Traxxas part? — Yes, absolutely. This TRX4994 is an original Traxxas factory component manufactured to the same specifications and quality standards as the parts installed in new vehicles. As an authorised Traxxas retailer, RC Model Shop stocks only genuine components, not aftermarket copies or inferior alternatives.
- How difficult is it to install this spacer? — Installation difficulty depends on your mechanical experience and whether the transmission needs to be partially disassembled. Generally, this is an intermediate-level maintenance task that requires basic RC tools and mechanical knowledge. If you're unsure about installation, our team at RC Model Shop can provide guidance or recommend professional assembly services.
- Will using a genuine Traxxas spacer improve my RC car's performance? — This spacer doesn't directly increase speed or power, but it ensures your existing performance capabilities are delivered smoothly and reliably. By maintaining proper bearing alignment and spacing, it eliminates friction losses and prevents the grinding or noise that indicates drivetrain problems, thereby preserving your vehicle's intended performance.
