HRTE125X - Super Duty Differential Locker Spool TRA 2WD Elec

This product is a super‑duty aluminum differential locker spool designed to replace the open gear differential in Traxxas 2WD electric vehicles, providing solid locked action between the left and right drivetrain outputs. As a full locker spool, it eliminates differential action and forces both wheels to turn at the same rate, improving traction and acceleration in straight‑line and high‑traction situations such as drag‑style racing or loose surfaces. The CNC‑machined aluminum body offers increased strength over plastic or lighter spools, resisting deformation under heavy torque from brushless motors and high‑power setups. Anodized finish helps resist corrosion and wear while the precision machining ensures smooth mesh and reliable operation in the differential housing. Installation typically involves removing the stock diff gears and placing this spool assembly into the diff case.

• CNC‑machined aluminum construction for super‑duty strength and drivetrain rigidity.
• Fully locks left and right outputs for maximum straight‑line traction.
• Designed for Traxxas 2WD electric vehicles with 48‑pitch drivetrain layouts.
• Precision machined for smooth gear mesh and reliable engagement.
• Anodized finish improves surface durability and corrosion resistance.
• Direct replacement for the stock open differential gear set.
• Ideal for drag racing or high‑traction surface use where diff locking is beneficial.
