It fits 1\/10 scale 4X4 Slash vehicles and is supplied by Traxxas as a factory part number 6878A, making it straightforward to drop into place whether you're repairing a worn clutch or upgrading from a high-stall unit.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this slipper clutch affect on-track performance?\u003c\/h3\u003e\n\u003cp\u003eThe slipper clutch helps protect gears and drivetrain parts by allowing controlled slip when loads spike, smoothing power transfer during launches and rough terrain. It reduces sudden shock to transmission components and can make throttle inputs feel more predictable, especially on loose surfaces.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePreassembled for consistent engagement and reduced setup time\u003c\/li\u003e\n  \u003cli\u003eIntegrated 54-tooth, 32-pitch spur gear for correct mesh and alignment\u003c\/li\u003e\n  \u003cli\u003eDesigned to absorb drivetrain shock, extending component life\u003c\/li\u003e\n  \u003cli\u003eUseful for tuning wheelspin and traction response under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my Slash 4X4 and how easy is installation?\u003c\/h3\u003e\n\u003cp\u003eThe 6878A is made as a direct replacement for 1\/10 scale Slash 4X4 models, so compatibility is straightforward when replacing a factory slipper clutch. Because it ships fully assembled with the spur gear installed, installation is quicker than assembling individual components; basic tools and routine clutch adjustment are all that’s needed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFactory part number 6878A — matches supplier specs for Slash 4X4\u003c\/li\u003e\n  \u003cli\u003eShips fully assembled; minimal disassembly of your vehicle required\u003c\/li\u003e\n  \u003cli\u003eStandard clutch adjustment procedure applies for fine-tuning slip\u003c\/li\u003e\n  \u003cli\u003eNo additional spur gear purchase required — 54T included\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat maintenance and setup should I expect?\u003c\/h3\u003e\n\u003cp\u003eBecause the unit arrives assembled, initial maintenance is limited to proper clutch tuning and occasional inspection for wear or debris. Periodically check shoe condition, spring tension, and spur gear teeth for damage; light cleaning and re-lubrication will keep engagement consistent.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInspect shoes and springs after hard runs or collisions\u003c\/li\u003e\n  \u003cli\u003eClean gear teeth and mating surfaces to prevent grit buildup\u003c\/li\u003e\n  \u003cli\u003eAdjust slipper tension to balance traction and drivetrain protection\u003c\/li\u003e\n  \u003cli\u003eReplace worn parts promptly to maintain predictable behavior\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan this be used as an upgrade from a high-stall clutch?\u003c\/h3\u003e\n\u003cp\u003eYes — the 6878A is suitable as an upgrade from high-stall clutches, offering a preassembled package that brings a controlled slip characteristic and the correct spur gearing.
