The Smart-Tech kit’s 35% larger piston maximizes both engaging and holding capacity of the Sonnax 10-clutch system. Smart-Tech components give you the option to reduce line pressure for greater efficiency, or drop to seven frictions for less parasitic drag and improved heat dissipation while retaining 10-clutch capacity.
