HRMTT125MG - Steel Spool differential assembly Mini-T B 2.0 Drag

Steel spool differential assembly designed to replace the stock gear‑type differential in 1/18 scale stadium truck and buggy drivetrains. It locks the two axle shafts together so both rear wheels rotate at the same speed, improving traction in straight‑line acceleration and on low‑traction surfaces. Hardened steel construction and precision gear meshes enhance durability and consistent drivetrain performance under load.

• hardened steel gears and spool body provide increased strength versus plastic differential components

• locked spool setup forces equal rotation of both rear wheels for improved traction on loose or slippery surfaces

• precision machined gears maintain accurate mesh to reduce noise and drivetrain lash

• compact design fits directly into Mini‑T 2.0 and Mini‑B transmission housings

• steel construction resists wear and impact from aggressive driving conditions

• improves straight‑line acceleration stability and power delivery

• includes all internal hardware needed for direct replacement installation
