SHIBATA & R31 HOUSE GRK MULTI-USE REAR KNUCKLE(RED)(R31S334RD)

This is a new concept aluminum rear knuckle that can be used with both A-arm and H-arm specifications depending on the combination.

By making the axle hub unit and the knuckle base body separate structures, it is now possible to change the tread width and fine-tune the position of the axle axis by changing the spacer thickness.

The extension plate that supports the A-arm specification

In addition to the height of the pillow ball mounting position, it is also possible to change the pillow ball offset amount and the pillow ball protrusion amount, which was not possible with the mounting screw length, because it is a separate structure from the knuckle body.

This allows for higher-dimensional geometry settings that were not possible with conventional knuckles.

Even with the H-arm specification, the separate lower arm adapter can be rearranged to choose from two different heights for the lower arm pin attachment.

*Due to its structure and characteristics, this product is intended for advanced users.
