Yella Terra RPM – Proven Australian performance for your Ford V8.

 Why Choose RPM?

• Built to withstand around 400lbs* max open spring pressure
• Oversize full-complement caged bearings designed for oscillating (rocking) loads, paired with oversize precision ground trunnions to reduce friction.
• Intricately balanced lightweight arms ensuring vital valvetrain stability - focusing attention on the harmony of the entire engine. 50% less oscillating nose weight eliminates valve float in upper RPM range allowing for higher rev ceiling.
• Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat.
• Proven bolt-on Pedestal mount design without any further cylinder head modification.
• Chrome moly steel hardened and ground roller tips of generous diameter (positively retained by internal circlip) preventing abrasion of valve tips and guides commonly seen with non-roller tip rockers. Allows for smoother, quieter operation. Maintains lash and reduces necessary and tedious engine maintenance.

WARNING:

• These rockers are recommended to a open spring seat pressure of 380-400 lbs.
• Use as a replacement for factory heads with factory lightweight springs.
• Not recommended with flat tappets/solid lifters
