GPM for Arrma 1/16 Mini KRATON 3S 4140 Carbon Steel Front & Rear Diff Outdrive

Upgrade your ARRMA 1/16 MINI KRATON 3S racing truck drivetrain for unparalleled precision and durability! These front and rear differential outdrives are CNC-machined from premium 4140 chrome-molybdenum alloy steel, delivering significantly enhanced strength and impact resistance compared to stock powder-metallurgy components. This ensures stable power transfer even during high-intensity driving. Perfectly compatible with CVD or dogbone driveshafts featuring 2mm pins, it directly replaces OEM part numbers #ARA311193 and #ARA-3294 for a plug-and-play installation.Core Advantages:Material: 4140 carbon steel with surface hardening for wear and impact resistance, effectively preventing gear tooth stripping and cup-end indentation.Ultimate Smoothness: Precision-fit clearances minimize power loss, delivering silky-smooth acceleration and steering precision.Fully Compatible: Engineered specifically for the ARRMA 1/16 MINI KRATON 3S Series (models ARA2508S/ARA2508), suitable for both front and rear differentials.Complete Replacement Set: Package includes 4-piece Diff Outdrive set for simultaneous front and rear differential replacement, significantly enhancing drivetrain reliability.

• 【Precision Compatibility, Hassle-Free Replacement】 Specifically engineered for RC car differentials (front/rear universal), perfectly compatible with CVD or dogbone driveshafts featuring 2mm pins. Directly replaces OEM part numbers #ARA311193 and #ARA-3294, ensuring a simple and convenient upgrade process without additional modifications.
• 【Material Strength Upgrade】 Precision-manufactured from high-grade 4140 alloy steel (carbon steel), offering superior torsional strength and impact resistance compared to OEM powder metallurgy or standard steel components. Effectively prevents gear stripping or breakage under aggressive handling, engineered for ultimate performance.
• 【Ultra-Smooth, Precision Transmission】 Precision CNC machining ensures optimal clearance between the cup and transmission pins. Significantly reduces energy loss and hesitation during power transfer, delivering silky-smooth acceleration and steering precision with vastly improved handling feel.
• 【Exceptional Wear Resistance, Lasting Like New】 The surface undergoes special hardening treatment, greatly enhancing the metal's abrasion resistance. Even under intense driving in harsh race conditions with high dust and heavy loads, it effectively prevents the cup mouth from denting due to long-term wear, significantly extending the lifespan of the transmission system.
• 【Track-Proven, Built for Victory】 Whether tackling circuit races or off-road climbs, this upgraded differential cup provides the most reliable power transmission assurance. It's not just a replacement for wear parts—it's a critical upgrade that boosts overall drivetrain efficiency and stability.
