The SPEC Stage 4 clutch kit is a race-focused replacement clutch explicitly for 2004–2006 Scion xA and xB models. Labeled for unsprung race use only, this kit is intended for competitive applications where a heavy-duty stage 4 clutch is required rather than street comfort. It supplies the clutch components matched to those model years and should be used where race-oriented engagement is acceptable.
