This kit includes ALL the seals for a complete caliper refresh. Each kit does ONE caliper, two kits are required per axle.
Lucky enough to have a 356C or a Short Wheelbase 911/912? This is the seal kit for you. The 35mm Seal was the original design to slow the rear of your air cooled Porsche down. It was in service until the rear trailing arms were redesigned to accommodate for the LWB cars. Note this seal kit will not fit the rear of the early 911S featuring the Wide L Caliper.
