$980.00

Yella Terra’s RPM shaft-mount rocker system is a performance replacement for Holden 304 / 5.0L EFI V8 engines using VN-style cylinder heads. The 1.65:1 hydraulic full-roller design combines low oscillating mass with a rigid common-shaft layout for street and high-RPM applications.

Construction and valvetrain control

Set of 16 Australian-manufactured and assembled roller rockers.
1.65:1 rocker ratio with 5/16 in mounting hardware.
Yella Terra rates the set to 400 lb maximum open spring pressure.
Oversize full-complement bearings and precision-ground trunnions are designed for oscillating rocker loads.
Aircraft-grade aluminium arms reduce valvetrain mass and assist heat dissipation.
Hardened chromoly roller tips reduce valve-tip and guide wear.
Common-shaft mounting increases rocker stability and clamp footprint.
Yella Terra states approximately 50% less oscillating nose weight than the factory rocker arrangement.
Shim set is included and the system is designed to fit beneath factory rocker covers.

Pushrod length: Yella Terra advises checking pushrod length when the engine no longer uses a standard camshaft/lifter combination.

Application: Holden 304 / 5.0L EFI V8 combinations using VN-style heads. Confirm valve-train geometry and clearances during installation.
