Yella Terra Adjustable Pro Street Shaft Type Roller Rockers
To suit the Nissan P40 Petrol engines.
These rockers feature Modular shafts with a rocker arm ratio of 1.65. and Includes shafts, mounting pedestals and standard bolts. (Standard rocker ratio = 1.45:1)
The New rocker arms have been designed with extra strength needed to handle the Heavier valve spring.-Ideal for harsh street and strip applications, these rockers have got what it takes to last!
The new cup adjustment on the rocker will make it easier to get push rods made .
They also come with shims to set the rockers to the right height so the roller nose runs in the least amount of movement on the centre of the valve tip.
Designed for high revving street/strip applications. No other comparable product can compete with 600lbs* maximum open spring pressure whilst retaining factory size bolt-down hardware.
Manufactured and assembled in Australia using the highest quality materials and componentry consistent with those found in our Platinum race series.
The roller rocker assemblies are manufactured specifically for Petrol based Nissan P40 engines- NA and Turbo. The original shaft and mounting posts are retained and used.
We recommend you use the matching shaft YT 6770SHFT.
