910434 Rear caliper seal kit

For owners of late Ironhead Sportsters, this MCS rear caliper seal kit is an essential maintenance item. It is tailored specifically for 1979 to 1981 XL Sportster models, addressing the specific caliper design used during those years. Over decades of use, original rubber seals can harden and fail, leading to reduced braking efficiency or fluid loss. This kit, corresponding to part number 910434, provides everything needed to reseal the rear caliper and restore its performance. Keeping the rear brake in top condition is vital for safe riding, and this high-quality kit ensures your vintage Sporty has the stopping power it needs when you hit the pedal.
