43T Steel Differential Ring Gear & 10T Pinion Gear Upgrade for 1/7–1/8 RC Cars, Hardened Steel Diff Assembly with Reinforced Output Shafts (Black)

This 43T steel differential and 10T pinion gear assembly is designed for high-power 1/7–1/8 scale RC vehicles that require increased drivetrain strength and reliability. Manufactured from hardened steel and precision-machined for accurate gear mesh, this differential assembly delivers smoother power transfer, improved durability, and more stable performance under high-load conditions. The reinforced output shaft structure helps distribute stress more evenly during acceleration, braking, and hard landings, making it a solid upgrade choice for off-road bashing and performance-focused RC builds.

• Heavy-Duty Hardened Steel Construction Made from high-strength hardened steel for superior wear resistance and long-term durability under high-torque brushless power systems.
• Reinforced Output Shaft Design Upgraded output shaft structure improves load distribution and helps reduce the risk of failure during aggressive driving and rough terrain use.
• Precision Gear Mesh CNC-machined 43T ring gear and 10T pinion ensure smooth engagement, reduced backlash, and stable drivetrain performance.
• Differential Assembly Upgrade Complete differential assembly designed as a direct replacement or performance upgrade for RC vehicles using 43T differential systems.
• Built for High-Performance RC Use Ideal for off-road bashing, high-power setups, and demanding RC driving conditions where drivetrain strength matters.
