Overview
The Traxxas Differential gasket and x-ring set (TRX8680) is an essential maintenance and upgrade component for owners of high-performance Traxxas RC vehicles, particularly the Sledge belted 1/8 scale monster truck and E-Revo 2.0 platform. Whether you're a dedicated RC enthusiast running your brushless RC car on challenging terrain or a weekend basher pushing your vehicle to its limits, differential maintenance is critical to keeping your transmission system operating smoothly and reliably. This genuine Traxxas spare part package provides you with all the sealing components necessary to maintain, repair, or upgrade your differential assembly, ensuring your RC truck or monster truck maintains peak performance in all conditions.
Differential gaskets and x-rings are crucial components that prevent fluid leakage and maintain proper seal integrity within the differential housing. Over time, factory seals can wear, compress or degrade due to heat, pressure and the demands of off-road driving. By replacing these components with genuine Traxxas parts, you're investing in the longevity and reliability of your RC vehicle's drivetrain. This maintenance item is perfect for RC hobbyists across the UK who demand professional-grade performance from their equipment, whether they're tackling rocky terrain, muddy trails or competitive courses.
The TRX8680 package is specifically engineered for compatibility with Traxxas Sledge platform vehicles and the E-Revo 2.0, two of the most capable and popular 1/8 scale brushless RC monster trucks available today. If you're experiencing differential leaks, performing scheduled maintenance, or undertaking a complete differential rebuild as part of your RC vehicle's service plan, this genuine Traxxas component set provides exactly what you need to restore your drivetrain to factory specifications.
Key Features
- Complete Differential Seal Kit — This package includes everything needed for proper differential sealing, featuring two precision-manufactured x-rings that serve as the primary dynamic seals within the differential housing, preventing fluid loss and maintaining proper lubrication of internal gears and bearings.
- Precision Metal Washer — The 12.2x18x0.5 metal washer (1 piece) provides a rigid backing surface for the primary seal, distributing clamping force evenly and preventing gasket deformation under the high pressures generated during aggressive driving and cornering.
- PTFE-Coated Washer for Superior Performance — The 12.2x18x0.5 PTFE-coated washer (1 piece) features a polytetrafluoroethylene coating that reduces friction between the washer and seal surfaces, extending seal life and improving differential efficiency by reducing drag and heat generation.
- Genuine Traxxas Engineering — These are authentic Traxxas factory components manufactured to exact OEM specifications, ensuring perfect compatibility and reliable performance with your Sledge or E-Revo 2.0 differential housing without any modification or adjustment.
- Professional Maintenance Essential — Proper differential sealing is fundamental to preventing fluid weeping, maintaining differential fluid levels, and protecting the precision internal gears from contamination, corrosion and premature wear that compromises off-road performance.
- Cost-Effective Reliability — Rather than replacing an entire differential assembly, this maintenance kit allows you to refresh the sealing surfaces and restore like-new performance at a fraction of the cost, making it an economical choice for regular maintenance routines.
Technical Performance
The Traxxas TRX8680 differential service kit is designed for the demanding requirements of 1/8 scale brushless RC monster trucks, which generate substantial torque and rotational forces that place significant stress on sealing systems. The x-rings included in this kit are precision elastomer components engineered to maintain their shape and sealing capability under continuous pressure cycling, temperature fluctuations and the contamination challenges of outdoor RC driving. The dual-washer system — combining a standard metal washer with a PTFE-coated variant — represents professional-grade engineering that addresses both the mechanical and frictional aspects of differential sealing. The metal washer provides the necessary structural support and force distribution required to maintain consistent clamping pressure on the x-rings, whilst the PTFE coating dramatically reduces friction and heat generation within the seal assembly itself. This dual-approach design is particularly important for high-performance applications like the Traxxas Sledge, which features brushless motor systems delivering maximum power to all four wheels through the differential, and the E-Revo 2.0, which is engineered for extreme off-road capability. The 12.2x18x0.5 dimensions are precisely matched to the differential housing geometry of these vehicles, ensuring perfect fit and optimal sealing performance. Traxxas Marine Grease is recommended when installing these components, as the differential operates in a moisture-rich environment on trail courses and during wet-weather RC driving, and the marine-grade lubricant maintains superior corrosion resistance and seal compatibility. This maintenance kit represents the same quality standards found throughout Traxxas' transmission systems, where precision engineering and material selection directly translate to reliability and extended drivetrain lifespan.

Frequently Asked Questions
- When should I replace the differential gasket and x-rings on my RC truck? — You should inspect and replace differential seals whenever you notice fluid weeping from the differential housing, or as part of regular preventative maintenance every 12-24 months depending on usage frequency. If you're performing a complete differential service, rebuilding after a differential failure, or upgrading to fresh internal components, replacing the seal kit at the same time ensures optimal performance and prevents premature seal failure from new components working against worn seals.
- What is the difference between the metal washer and the PTFE-coated washer? — The standard metal washer provides structural support and even force distribution across the seal surfaces, whilst the PTFE-coated washer reduces friction between moving surfaces, generating less heat and extending seal life. Most professional builds use both together as included in this kit for maximum performance and durability.
- Can I use these seals on other Traxxas models? — The 12.2x18x0.5 dimensions are specific to the Sledge and E-Revo 2.0 differential housings. Other Traxxas models may use different seal sizes, so check your vehicle's parts diagram or consult the Traxxas technical support resources to verify compatibility before purchase.
- What lubricant should I use when installing these seals? — Traxxas Marine Grease is the recommended lubricant for differential service on all Traxxas vehicles. The marine-grade formulation provides superior corrosion resistance and maintains seal compatibility in moisture-rich trail and off-road environments that standard greases cannot adequately protect against.
- Do I need any special tools to install this seal kit? — Most Traxxas differential work requires only metric hex drivers and standard RC maintenance tools. The Traxxas 8712 7-Piece Metric Hex and Nut Driver Essentials Set is recommended for working on Traxxas models, and the optional 8720 large handle allows you to apply more torque with less effort when tightening and loosening differential fasteners.
- Is this suitable for beginners? — Differential service requires mechanical aptitude and careful attention to assembly sequence and torque specifications. Whilst not extremely difficult, this is recommended for intermediate to advanced RC builders who are comfortable disassembling and reassembling transmission components. Beginners should consult detailed online guides or seek assistance from experienced RC technicians at hobby shops.
