Before you purchase this kit, please read our recommendations for additional parts.
Recommended Parts with this Job:
#1: JPM Spin off Disk. This low profile, double sealed spin off disc will disperse any water that bypasses the bowl seal. This spin off disc is required when using the bowl seal conversion kit, as the larger OEM style does not have enough clearance for the seal plate locking nuts. If your HCM has the brake feature, this spin off disc is not required.
#2: Upper Motor Oil Seal: This is a secondary seal that prevents liquid and debris from entering the upper motor housing. This part is also included with the HCM rebuild kit.
