The Vanquish Currie Portal F9 SCX10 II Rear Axle Kit is an all inclusive axle assembly that creates extreme amounts of ground clearance under the center of your axle. By increasing the pumpkin clearance by 1/2"+ (13mm), it creates the equivalent of running a tire that is over 1 inch taller than what is on your rig. But the real advantage of the Vanquish Currie F9 Portals is the gear reduction inside the portal (1.67:1), that can be tuned with optional gear sets (1.4:1 Overdrive). By adding reduction at the portal, less torque is transferred through the other upstream components in the drivetrain. These axles are a direct replacement to any Axial AR44 axle, using all stock links. NOTE: Requires the use of a 350 SLW hub or greater on Vanquish 1.9 wheels, Incision wheels will require a #4 or greater. Other wheel manufacturers offsets will vary. Axles must be used in pairs, you cannot run a front portal axle without a rear and vice versa. Overdrive gear sets are recommended for use in the front axle only. Featu
