Improved Shifting
Installed and shifting is more crisp but not too aggressive that it slams during gear changes. Vehicle is 1990 F150 5.0 4x4 E4OD with 175000m. I got the .331" diameter kit for 6 cyclinders and small V8's. I contacted Sonnax to confirm size and this size is correct for small block V8's. The .372 diameter size is for big block V8's.
