Piston Selection

3.5L, 3.7L and 5.0L (4V) Engines

1. Engines are equipped with a single grade size piston.

6.2L (2V) Engines

NOTE: The cylinder bore must be within the specifications for taper and out-of-round before fitting a piston.

2. Select a piston size based on the cylinder bore.





3. NOTE: For precision fit, new pistons are divided into 3 categories within each size range based on their relative position within the range. A paint spot or specific size grade on a new piston indicates the position within the size range.

Choose the piston with the correct paint color or specific size grade.

- Refer to the appropriate information for the procedure.
