Next-Level Diff ProtectionEngineered for Extreme Arrma Bashing
Upgrade your vehicle's drivetrain with the high-performance Arrma Aluminum Differential Carrier Case BLX 3S 4S. Designed to handle intense brushless motor power, this heavy-duty diff housing eliminates gear flex and prevents stripped internal gears. It is the ultimate durability upgrade for extreme RC car enthusiasts pushing their 3S and 4S power setups to the limit.
Heavy-Duty Drivetrain ReinforcementUncompromising Strength for BLX Models
The Arrma Aluminum Differential Carrier Case (BLX 3S 4S) provides precision alignment and structural stability for your differential gears. Factory stock plastic diff cases can flex under high torque, leading to premature gear failure during aggressive jumps and high-speed off-road driving. Machined from high-grade aluminum, this premium RC car upgrade part retains fluid tightly while maintaining exact gear mesh under extreme loads, ensuring your Arrma 3S or 4S RC monster truck stays on the track longer with minimal maintenance.
