What is the main advantage of the 15% stronger diaphragm spring?

The 15% stronger diaphragm spring increases the clamping force on the clutch plates. This results in a larger surface area for engagement and greater torque capacity, helping your clutch handle more power reliably.

Does this kit include everything needed for a clutch replacement?

This kit includes the fiber plates, steel plates, and the stronger diaphragm spring. It is designed as a stock replacement, but it's always a good idea to check your service manual to ensure no other specific hardware or fluids are required for your particular model.

What does 'stock replacement' mean for this clutch kit?

Stock replacement means this kit is designed to fit and function like the original clutch components in your 1985-1989 Harley-Davidson Big Twin. It should install without requiring modifications to your existing clutch basket or related parts.
