Product Description

The Brian Crower BC3929 Exhaust Valve Guides are designed for the high-performance RB26DETT engine, offering exhaust side valve guide support that withstands intense heat and high RPM demands. Made from high-grade manganese silicon aluminum bronze, these guides provide exceptional durability, resisting cracking and corrosion in the harsh exhaust environment.

With a 7.0 mm stem diameter and a complete head set of 12 guides, this product covers all exhaust valves in the RB26DETT cylinder head. These guides pair seamlessly with Brian Crower stainless exhaust valves, restoring valve seal and ensuring stable operation under load. Installation will require removing the cylinder head, pressing in new guides, and ensuring proper lubrication and fitment.

Fitment is confirmed for model years **1990 through 2002** with the RB26DETT engine. 2025 coverage unconfirmed beyond these years. Ideal for engine rebuilds, restoring worn exhaust guides, or upgrading valvetrain components for performance reliability.
