Q:Does this product include main bearing and seal?
Christopher J.
A:BEST ANSWERHi Christopher, I'm glad to assist you. No, it is the harmonic balancer only (also called the crankshaft pulley). It is a universal part as well, not a direct-fit vehicle-specific part. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, and engine size). Still, it is best to call our parts specialist (for real-time, live, and immediate assistance) on our toll-free number, 1-866-529-0412 (Monday through Sunday). Show less
