This 8-piece set is a direct replacement for the TTMRC RR 4-valve GY6 cylinder head. It covers all four valves (2 intake, 2 exhaust) in one kit.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eKeepers (also called cotters or collets) lock the spring retainer to the valve stem groove. Worn, rounded, or mismatched keepers can let a retainer slip. On a high-compression 4V head, a dropped valve usually means a new piston, valve, and possibly a head. If you’re rebuilding, refreshing springs, or going to lighter retainers, put in fresh keepers too.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eComplete set: 8 keeper halves = 4 pairs, enough for every valve on the TTMRC RR 4V head\u003c\/li\u003e\n\u003cli\u003eFactory-correct taper for a secure lock between retainer and stem\u003c\/li\u003e\n\u003cli\u003eHardened steel construction \u003c\/li\u003e\n\u003cli\u003eDirect OEM-style replacement for the TTMRC RR 4V head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eQuantity: 8 pieces (4 pairs)\u003c\/li\u003e\n\u003cli\u003eFits valve stem diameter: 5.0mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eTTMRC GY6 RR 4-valve cylinder head\u003c\/li\u003e\n\u003cli\u003eGY6 125\/150\/180cc engines running the TTMRC RR 4V head [CONFIRM displacement range]\u003c\/li\u003e\n\u003cli\u003eNot for stock 2-valve GY6 heads.
