Product Details

If you're rebuilding the top end of your 1993-2001 Nissan Altima or 1991-1998 Nissan 240SX with the KA24DE engine, these Brian Crower spring seats are a key component. They sit at the base of the valve spring, providing a solid, flat surface for the spring to rest on within the cylinder head. This ensures consistent spring height and proper valve spring tension, which is crucial for reliable engine operation, especially when you're pushing the engine harder.

Brian Crower is known for making well-built engine components, and these spring seats are no exception. They are made from durable materials designed to withstand the heat and pressure inside the engine. Proper installation of these seats helps maintain the intended valve spring geometry, preventing premature wear and ensuring your valve train functions as it should. This is a small but important part of getting your engine's valvetrain set up correctly.
