Brian Crower Nissan RB26DETT 7.0mm Exhaust Valve Guides (Quantity of 12)

These 7.0mm exhaust valve guides from Brian Crower are made from a durable cast iron material, chosen for its ability to withstand the heat and wear found in performance RB26DETT engines. When you're rebuilding the top end of your Nissan's legendary inline-six, ensuring proper valve sealing and movement is critical, and these guides play a key role in that. They are designed to fit the 7.0mm stem diameter of your exhaust valves, which is important for maintaining the correct clearance and preventing valve drop.

Brian Crower is known for making well-built engine components, and these valve guides are no exception. They are manufactured to precise tolerances, which helps ensure a smooth operation for your exhaust valves. This attention to detail means you can expect consistent performance and reliability from your engine rebuild. Having a good set of valve guides helps prevent oil from leaking past the valve stem and into the combustion chamber, which can cause smoking and reduced performance.

This set includes 12 valve guides, enough for a full engine build on your RB26DETT. Proper installation is key, so make sure to follow the manufacturer's recommended procedures for fitting these guides into your cylinder head.
