Precision-machined manganese bronze guides designed for easy installation and durable performance. 🔧
Manganese bronze is softer than nickel aluminum bronze and offers excellent heat conductivity, which promotes long valve life.
Guides can be reamed with a battery-operated or electric drill and finished with a high-quality ball hone, eliminating the need for expensive honing equipment required for harder bronze guides.
Machined to accept OEM and aftermarket seals, these guides will require machining for seal installation and the use of compatible valve seals. Made in the USA.
