The VS4-10 Phoenix Portal RTR Phoenix Edition is equipped with the VFD Twin, incorporating Selectable Overdrive Shifting and 3-position dig ready (servos not included*) into one compact package. The molded F10 Portal Axles utilize a high clearance design which minimizes the size of the pumpkin and maximizes clearance around the C-hub and knuckle. Connecting the VFD Twin to the F10 Axles are the ISD10 driveshafts. The ISD10 Driveshafts have machined CV style joints at each end with molded splined shafts between them for smooth, quiet and efficient performance. The large 8mm bore S8E shocks included dual X-Ring cartridge and scale threaded caps with a sealed upper bleeder screw. S8E preload adjustment is a breeze with the threaded shock bodies and collars.
