This is a brand new, very high quality, and very correct US Made 129 tooth ring gear. This is for the 1953 through 1971 jeeps. These include the M38A1, M170, CJ3B and CJ5. This will fit some earlier jeeps between the years of 49 and 53 as well but make sure to count the number of teeth. Why replace a flywheel when you can simply change the ring gear.
NOTE: Please count the teeth on your original before ordering. Remember there are three different styles of ring gear.
