Use the compatibility data below to confirm fitment against your V.I.N.

What does ERC9055 do?

The ERC9055 rocker transfers camshaft movement to the inlet valve mechanism on the left-hand bank of the cylinder head. Mounted on the rockershaft, the rocker pivots to convert the cam lobe profile into axial motion at the valve stem, allowing the inlet valve to open and close in time with the engine cycle. Correct rocker geometry and secure mounting on the rockershaft are necessary for consistent valve timing and valve seating on 2.5L 4-cylinder naturally aspirated diesel engines fitted to Defender models from 1987 to 2006. When replacing a single rocker, inspect the rockershaft and neighbouring rockers for wear or damage to maintain uniform valve operation across the head. If available, use the vehicle V.I.N. and the compatibility data below to confirm this part matches the original fitted component.
