Say goodbye to glued-on flanges. Introducing the next evolution in RX4E differential pulley design!
Introducing the RRP V2 Wide Performance Pulley, designed for improved reliability and long-term performance across the RRP RX4E, RX4D, RMX, RMX97, Yokomo MR4BC, and MX4 platforms.
 
This innovative design features integrated, precision-machined pulley flanges. No glue, no loose flanges, and no worries about component separation during operation.
 
Designed as a performance upgrade and replacement solution for worn or aging Yokomo ZG-503 pulleys, our pulley increases differential ball support from 12 to 14 × 3/32-inch differential balls, distributed to promote even contact and help reduce localized wear on the differential rings. 
 
Key Features
Integrated Flange Design – Eliminates glued-on flanges for improved structural integrity
33T Wide Differential Pulley – Designed for compatible Yokomo differential systems
14-Ball Differential Support – Accommodates 14 × 3/32-inch differential balls versus the standard 12-ball configuration
Machined POM – Durable white engineering material
Replacement & Performance Upgrade – An alternative to worn or aging Yokomo ZG-503 pulleys
