{"product_id":"shaft-rocker","title":"Shaft - Rocker for Defender (1986 – 2006) – 611659L","description":"\u003cp\u003eThe rocker shaft is a core component of the Rover V8 overhead valve system, providing the central axis around which the rocker arms pivot to actuate the intake and exhaust valves. On the Rover V8, worn or damaged rocker shafts commonly result in increased valve train noise, oil pressure loss to the rocker assembly, and uneven valve operation leading to misfires or reduced power. Correct replacement is essential to maintain proper rocker arm geometry and oil distribution across the cylinder head.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured to original specification dimensions for accurate rocker arm alignment on the Rover V8 engine\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the existing shaft - no modification required during installation\u003c\/li\u003e\n\u003cli\u003eCompatible with OEM-specification rocker arms and pedestals used across the Rover V8 cylinder head\u003c\/li\u003e\n\u003cli\u003eThe Rover V8 uses two rocker shafts per engine (one per cylinder head) - confirm quantity required before ordering, and inspect rocker arms and pedestals for wear simultaneously\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eThis rocker shaft fits the Rover V8 engine as used in the Defender (1986–2006), Discovery 1 (1989–1998), Discovery 2 (1998–2004), Range Rover Classic, Range Rover P38 (1995–2002), and Series 3 with the 3.5 V8 petrol engine.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
