Lighter drivetrain weight contributes to improved throttle response

��The use of Delrin cups makes the suspension smoother. contributing to improved traction.
��The overwhelming lightness improves acceleration speed and cornering performance.
��The use of ball differential pulleys increases the options for pulleys from other companies. increasing the range of secondary reduction ratios.
��The Delrin spare cup joints can be directly replaced with the ART2741 RX-J lightweight solid differential kit.

��The spring effect of the O-ring eliminates play when installing the differential cup.
��Installing a ball differential pulley eliminates vertical vibration of the pulley.

Note: A separate pulley is required. We recommend using it for a ball differential.
