This component strengthens the drivetrain by replacing stock differential gears with a durable steel locker spool. It locks the differential to provide equal power to both wheels on the axle, improving traction during acceleration and off-road maneuvers. Hardened steel construction resists wear and deformation under high torque loads common in aggressive driving. Precision machining ensures smooth meshing with existing drivetrain components and proper alignment within the differential housing. Designed for either front or rear differential positions, it provides versatile installation for 1/10 scale monster trucks. The component maintains compatibility with stock mounting hardware and gearbox dimensions. This upgrade enhances traction, control, and drivetrain reliability for heavy-duty off-road use. Hardened steel construction for improved drivetrain strength and durability Locks front or rear differentials in 1/10 scale Traxxas Maxx vehicles Provides equal torque distribution to both wheels for enhanced traction Precision machined for smooth engagement with differential gears Compatible with stock differential housings and mounting hardware Resistant to wear and deformation under high torque loads Manufactured through precision small scale metal machining processes
