The FX250 SS Series is a factory fit twin disc replacement for the S55, positioned between the factory twin disc and the race-oriented 725, 850 and 1000 Series kits. Each DLX disc runs Fiber Tough friction on the pressure plate side and steel-backed organic friction on the flywheel side, giving more holding capacity than a full-face Kevlar disc while staying street friendly. The stamped steel cover replaces the self-adjusting factory unit, disc diameter grows from 8.5 in to 9.5 in, and the kit is about 10 lbs lighter than stock.
