CH-CC-6 is a modified version of CH-CC-4 and is used in 10-3/4" lockup converters with '96-later 5.9L engines. Since the engine external balance weight is mounted on the flexplate in this application, CH-CC-6 has undercuts to allow clearance for the balance weight. The cover is furnished with no weights or ring gear and must be balanced after assembly.
Use CH-CC-4 for the early 1992-95 5.9L engine where the balance weight is mounted to the converter and a 2° offset hole is used for the flexplate.
