Replace the clutch once with Honda parts and decided to try something different this kit really impresses me I like the heavy duty springs would use it again and again 4,000 miles on it without a problem

It works good for a quarter of the OEM price, I would totally recommend buying tusk products for the vast majority of things due to their commitment to making good products at great prices. Overall a very good purchase and I'm very happy with it.
