YELLA TERRA LS3 ULTRALIGHT 1.8 HYDRAULIC SHAFT ROCKERS

Yella Terra Ultralite hydraulic shaft bolt on roller rocker set, to suit LS3/LS9/L76/L77/LY6/L94/L92/L98/LC8/LC9/LH9/LMF/LH9. These rockers are a "bolt on" and require no machining. The come as a complete set with all hardware including the rubber spacer/gasket for additional clearnace that may be required if using factory rocker covers. 

These rockers feature 8.0mm bolts, with a rocker arm ratio of 1.8.

The rocker arms used on Yella Terra and Street Terra roller rockers are infinitely stronger than standard pressed steel arms providing the best in resistance to bending and breakage under high spring pressures at high RPM's. Pressed steel rocker arms, in high performance applications, are prone to failure, A high rate of fulcrum wear, flexing, cracking, splitting and breakage are common problems that will result in power loss or possible piston failure due to detonation of the incoming air/fuel charge. Other Yella Terra rocker components such as the trunnions, posi locks and bearings greatly enhance valve train durability in performance applications.

The use of needle roller bearings at the rocker fulcurm combined with roller tip at the valve greatly reduces horsepower robbing friction in the valve train to provide a measurable power increase over standard rocker systems.

The reduction in friction with roller rockers has additional benefits of reducing the operating temperature and foaming effect of engine oil to provide a cooler running engine.
