Yella Terra Rover V8 Roller Rocker Range

YT 6000 – Street & Performance
The YT 6000 is our proven Rover V8 factory replacement and performance roller rocker, designed as a strong and reliable upgrade for street, performance and general engine builds. It is available with either 3/8" or 5/16" cup adjusters, allowing engine builders to use commonly available pushrods or select 5/16" tapered pushrods where additional clearance is required. The YT 6000 is the ideal choice where durability, versatility and straightforward installation are the priorities.

YT 6000UL – Ultralite High RPM
The YT 6000UL Ultralite is designed specifically for higher-RPM applications where reducing valvetrain mass is important. Material is strategically removed from both the valve nose and the pushrod/cam side of the rocker, reducing reciprocating valvetrain weight and inertia. This helps improve valve control at higher engine speeds and can reduce the need to compensate with unnecessarily heavy valve spring pressures. Available with both 3/8" and 5/16" cup adjusters, the 6000UL is an excellent choice for performance and high-RPM Rover V8 combinations.

YT 6305 – Race Only
The YT 6305 sits at the top of our Rover V8 range and is a purpose-built Race Only rocker system for serious competition engines. Rather than focusing primarily on weight reduction, the YT 6305 is engineered for maximum strength, rigidity and valvetrain stability under extreme operating conditions. It is intended for high-RPM, high-load and aggressive race combinations where increased valve lift, spring pressure and sustained competition use place significantly greater demands on the rocker system.
