Fitment Notes

• Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
• The matching cam follower (hydraulic lash adjuster / lifter) for this rocker arm is SY-K233 — order both together if both are being replaced as a set.
• Sold individually — count rocker arms per cylinder head before ordering. The 2.5/2.8 CRD DOHC engines use multiple rocker arms per cylinder.
• Chrysler, Dodge, and Jeep all use the same Stellantis part number (05066780AA) — the rocker arm is identical across all three marques.

Installation / Use / Maintenance Tips

• Rocker arm replacement must be carried out by a qualified workshop with the correct service manual — incorrect assembly or torque can cause valve damage or oil starvation.
• Inspect the camshaft lobes and the matching cam followers (SY-K233) at the same time — a worn rocker arm often indicates wear elsewhere in the valvetrain.
• Pre-lubricate the new rocker arm and roller bearing with clean engine oil before fitting.
• Tighten all valve cover bolts and rocker shaft fasteners to the manufacturer's torque specification in the correct sequence.
• Check oil pressure at idle and operating speed after assembly; abnormal lifter tick or noise indicates a follower or oil supply issue that must be resolved before extended running.
