This is an optional Revolution Design Racing Products Aluminum C-Hub Set, and is intended for use with the Durango DEX210, DEST210 and DESC210 vehicles. These hubs feature two additional outer camber link mounting positions for a total of four mounting points! Additionally, the hubs reduce the front track width by 1mm per side so you can run wider front tires and remain within legal width. The C-Hubs are compatible with the stock caster inserts, as well as the RDRP0041 0° inserts. They are CNC machined from 7075-T6 aluminum for increased durability, and are anodized black, then laser etched for stealthy good looks.
