Compatibility
Please note: this spring is specific to vehicles with 9-inch drum brakes. Later models with 10-inch brakes use a different spring part number. Check the drum diameter (cast into the iron) to be certain.
Historical context
The 9-inch drum brakes were standard on early post-war Jeeps and remained in use until the early 1950s, when larger 10-inch brakes were introduced for improved braking capacity.
