High, Carbonite® PowerPack® clutch kit with extra plate

Incl. 9x single-sided Carbonite friction plates with external teeth, 9x single-sided Carbonite friction plates with internal teeth, 1x double-sided Carbonite friction plate. Complete Carbonite® PowerPack® 'Maximum Effort' clutch kits with friction and steel plates. Developed to withstand the power and torque of Big Inch / High Performance engines on today's streets. This Carbonite clutch kit includes an additional friction plate and a steel drive plate, increasing the clutch area for greater holding capacity. The friction plates are coated with 3M carbon-based material, capable of withstanding higher temperatures and offering a superior friction coefficient to any other material currently available.
The steel drive plates are 'Performance Steel™', with a surface roughness value Ra (average roughness) of only 2-10 micro inches. Conventional steel has an Ra value between 15 and 25 micro inches. A microscope will show fewer peaks and valleys on Alto's 'Performance Steel™'. This improves performance, durability, mating and offers a longer service life and cooler running.
