This is the top shoe spring that is used on 10" brake setups on all V6 and some 4 cylinder models 1966-1971. The shoe is at the top of the shoe and goes from the stud to either shoe (one per shoe).
Note: On 1966-1971 CJ5 and CJ6 models with the 4 cylinder always check the brake size because they also had 9" brakes.
2 Required per Drum or 8 Required per Jeep.
