Description

Yella Terra Ultra lite shaft Rocker arms bolt on roller rocker set, to suit LS3,L98 These rocker arms come as a complete set with 8.0mm bolts.

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.

When fitting YT Adjustable Rockers to LS1, LS2, LS3, LS7 & LSX based engines, the heel of the rocker may require clearance at the inner edge of the cylinder head valve cover rail. The YTP-YT-5123 valve cover spacer incorporates special scalloped sections which provide the required clearance and allows the fitment of the original factory covers for an OEM look.
