Aluminum vertical rear upper support – Shibata -R31S341 various colours
THE vertical rear upper support Shibata R31S341 is an optional aluminum part specially designed for chassis GRK5 And GRK4.
Combined with thesingle-arm upper axle GRK RWD (R31S118), it allows you to convert the rear suspension system of a double point of support towards a single-arm attachment on the shock absorber tower, thus improving the rigidity, there lightness and the ease of maintenance of the rear axle.
This development also optimizes chassis response and precision drift behavior
