HRAET80S01 No. 45 Steel Diff Out Drive 18t

Machined as a No. 45 steel differential out drive with an 18 tooth spline interface, this component transfers torque from the internal diff gear to the axle shafts in 1/18 scale RC vehicles. The hardened steel construction resists wear and deformation under high load, maintaining consistent engagement and reducing slop in the drivetrain. Precision machining ensures accurate tooth profile and smooth rotation, helping improve drivetrain efficiency and response. Ideal for performance and tuned builds, it enhances overall durability and reliability.

• No. 45 steel construction increases strength and resists wear under load
