Some say : R-Box installed a cup holder or a cookie jar on the tunnel.
But : On top of the Sadev gearbox are a gear lever, powershift sensor and an air release valve. All this is very close ti the tunnel so we needed to make room to install all these parts.
For this reason we installed an extra “box” on top of the tunnel. We also provided a little more room for the gear lever which resulted in the final design.
