SPEC Stage 4 Clutch Kit Mustang GT 2005-08.
The '05-'06 Mustang uses a concentric slave cylinder instead of a conventional throwout bearing. Therefore these kits will not include a throwout bearing. SPEC can ship a bearing with the kits by request for an extra $125. Choose the Low pedal Requirement option by typing 'LPR' in the notes section of the order form. For 8 bolt crank upgrades, use SF48A and SF48S flywheel numbers.
