Enginetech CHS1058L Cylinder Head Spacer Shim for Ford SOHC - 4.0L

The Enginetech CHS1058L is a precision cylinder head spacer shim made from .020" cold rolled steel designed for Ford 4.0L SOHC engines. This critical component is essential for engine rebuilds where cylinder head or block surfaces have been machined or resurfaced.

Key Features:

• Restores valve train geometry, valve clearance, original compression ratios, and cam timing to factory specifications
• Solves common problems including lack of valve train geometry, compression ratio creep, and timing chain flutter
• Manufactured from durable .020" thick cold rolled steel
• Precision-cut for accurate fitment on Ford 4.0L SOHC engines
• Single shim per package

Installation Notes:

• Install on the block side with the cylinder head gasket on top
• Use with conventional head gaskets only
• Apply sealer between shim and block surface

This shim is recommended for engines where machining has occurred beyond factory specifications, ensuring proper engine geometry and performance after reassembly.
