{"product_id":"seat-valve-spring","title":"Seat - Valve Spring for Discovery 3 (2005 – 2009) Qty 32 – 3598716","description":"\u003cp\u003eThe valve spring seat is a precision component that locates and retains the valve spring at the base of each valve assembly in the cylinder head. On the 4.4 AJ V8 and 4.2 supercharged V8 engines, these seats maintain correct spring geometry and prevent metal-to-metal contact between the spring coils and the head surface. Worn or damaged seats can cause erratic valve timing, increased wear on the spring and stem seal, and eventual valve train noise.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSupplied in the quantity of 32, covering all valves across a complete V8 cylinder head set\u003c\/li\u003e\n\u003cli\u003eDesigned to seat at the base of each valve spring, ensuring correct spring alignment and load distribution\u003c\/li\u003e\n\u003cli\u003eOEM specification part, directly compatible with Land Rover AJ V8 engine architecture\u003c\/li\u003e\n\u003cli\u003eWhen replacing valve spring seats, inspect valve stem seals and springs simultaneously as these components wear at similar rates\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eThis part fits the Discovery 3 (2005–2009) 4.4 AJ Petrol V8, Range Rover (2002–2009) 4.2 V8 Supercharged and 4.4 AJ Petrol V8 (to VIN 6A000001), and Range Rover Sport (2005–2009) 4.2 V8 Supercharged and 4.4 AJ Petrol V8.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
