Alto Clutch Friction Discs for 1990-1997 Harley-Davidson Big Twin and 1991-2022 Sportster

Evo wheelies are good for the soul but not so great for the clutch. Trade slip for grip with a new set of friction discs.

  • Made in USA
  • 8 friction discs
  • For wet clutch
  • Meets or exceeds OEM specifications

If you haven't yet pulled your bike apart, bikes that use this kit also use a judder spring in the middle of the clutch pack. The brass rivets that retain it are prone to wearing and coming loose. Rather than replacing it, installing one extra plate and steel is a longstanding mechanical upgrade.

TC Bros. recommends the installation of an extra-plate kit if you wish to make this conversion—the additional friction plate and steel you need are included in that SKU. Learn a little more in our blog about your options if you're replacing a clutch.

  • 1990-1997 Harley-Davidson Big Twin
  • 1991-2022 Harley-Davidson Sportster with air-cooled engine
  • Must be used in conjunction with OEM spring plate (or equivalent) or sufficient alternating friction plates and steels to bring the clutch stack height to factory specification
  • 110-0077; replaces 37911-90, 18-8276, 1131-0465, 095752B, 1131-0425, 73146
