This aluminum rear hub carrier can be used commonly with the YD-2 series. The universal shaft with a short axle shaft for narrow scrubs is used, and the universal joint pin is positioned as far outward as possible, closer to the outer suspension arm pin, to activate the suspension movement and enable more direct movement. Conventional universal shafts can also be used by adding spacers, so you can feel the difference in movement by combining them.
This rear hub carrier set also features selectable upper and lower arm mounting positions, and by making the upper side a separate part, the length of the upper arm can be changed variably, making it easier to control the change in ground contact surface when rolling, which is an effective setting point, especially on surfaces such as P-tile. This is an effective setting point, especially on P-tile surfaces. The lower arm can be installed at 4 different heights, allowing for a wider range of roll center settings, and is an excellent match with the rear weight adjustment.
Upper arm mounting is a separate part, allowing a wide range of positional choices by adding hole positions, mounting orientation, spacers, etc.
The suspension arm pin has 4 hole positions to choose from, allowing for a wider range of roll center adjustment, and is a perfect match for bulkhead spacers, etc.
When using the bottom-most suspension arm mounting hole, the suspension arm may interfere with the inside of the wheel, depending on the wheel type. All mounting positions can be used with Racing Performer RP-6313 series wheels.
