This is a lower arm shaft developed to accommodate the use of other companies' φ3.0 hole diameter lower arms for GRK.
The total length is 49.0mm. The rear and length of GRK4 & GRK5 are the same.
Please use it in combination with the GRK φ3.0 suspension ball (R31S086), which is also on sale at the same time, and a spacer that corresponds to the same suspension pin diameter
