Frequently Asked Questions
- What Traxxas 4WD models is the TRX6879 compatible with? — The TRX6879 is compatible with a wide range of Traxxas 4WD vehicles including Slash VXL, Slash Ultimate 4x4 VXL, Rustler Ultimate VXL 4x4, 4TEC 3.0 Chevrolet Corvette Stingray (both silver and black variants), Ford Fiesta ST Rally BL-2S and VXL versions, and Stampede 4X4 HD VXL models. However, it is important to verify compatibility with your specific model before ordering, as some platforms use different differential specifications.
- Why would I need to replace my differential gears? — Differential gears experience continuous stress and wear during driving, particularly during aggressive cornering, high-speed running, and rough terrain bashing. Over time, gears can become worn, chipped, or damaged, leading to noise, slipping, inconsistent power delivery, and poor handling. Replacing worn differential gears restores optimal drivetrain performance and handling characteristics, ensuring your RC car UK setup maintains competitive performance and reliability.
- Is this suitable for beginners? — Whilst the TRX6879 is a genuine spare part for maintaining and repairing Traxxas vehicles, differential replacement is an intermediate to advanced maintenance task requiring mechanical knowledge, proper tools, and understanding of drivetrain assembly. Beginners should consult detailed build guides, instructional videos, or seek assistance from experienced RC hobbyists or specialist retailers before undertaking differential replacement.
- What is the difference between this and other differential options? — This is the genuine Traxxas rear differential assembly (part number TRX6879) specified for the models listed in compatibility documentation. Some vehicles may have been documented with incorrect part numbers in factory manuals, so always cross-reference your specific model documentation or contact Traxxas support to ensure you're ordering the correct component for your vehicle. Using non-genuine or incompatible differentials can result in poor fit, damage, or drivetrain failure.
- How do I install the TRX6879 in my Traxxas? — Differential installation involves removing the axle shafts, extracting the old differential assembly, and carefully installing the new ring and pinion gears with proper alignment and backlash adjustment. This process requires specific knowledge of your model's construction and access to detailed assembly documentation. Traxxas provides comprehensive build guides and parts diagrams for most models, and our team at RC Model Shop can provide guidance and support.
- What maintenance does a differential require? — Proper differential maintenance includes regular inspection for wear or damage, ensuring the slipper clutch is adjusted correctly to prevent gear damage during acceleration, using quality bearing oil or differential fluid as specified by Traxxas, and protecting the differential from extreme impacts or collisions that could damage the gears.
