Valve Spring - V8 is a cylinder head valve spring for the Rover 3.5L and 3.9L V8 petrol engine.

The valve spring seats between the cylinder head and the valve spring retainer, maintaining constant pressure on the inlet or exhaust valve to hold it closed against the valve seat and ensure positive closure after each cam lobe has actuated the valve. Correct spring rate is essential for reliable valve train operation across the full engine speed range.

Frequently asked questions

What does the Valve Spring (ERR4628LR) do?
The Valve Spring (ERR4628LR) is a cylinder head valve spring for the Rover V8 petrol engine. It seats between the head and the spring retainer, holding constant pressure on the inlet or exhaust valve to keep it closed and ensure positive closure after each cam actuation. Fitted across Land Rover Defender, Discovery, and Range Rover V8 engines.
Which V8 engines does this valve spring cover?
The ERR4628LR valve spring fits the 3.5L and 3.9L V8 on the Land Rover Defender up to 2016 and Discovery 1, the Discovery 2 V8, and the 4.0L and 4.6L V8 on the Range Rover P38 and Range Rover Classic. It also suits the Series 3 Stage 1 V8. Confirm your engine before ordering.
How many valve springs does a V8 need?
A V8 uses one valve spring per valve, so a full head rebuild typically needs a set of sixteen ERR4628LR springs across the eight cylinders. This part is sold individually, so order the quantity your job requires for the Land Rover Defender, Discovery, or Range Rover V8.
Should valve springs be replaced as a set?
Valve springs are typically replaced as a complete set during a head overhaul, since mixing old and new springs gives uneven valve control on the V8. Fit fresh ERR4628LR springs throughout when reconditioning the heads on the Land Rover Defender, Discovery, or Range Rover.
