Clutch Sprocket Bearing – Fits Harley Big Twin 1990-Later (OEM 37906-90) By Mid USA

Rebuilding the primary on your Big Twin?

This is the clutch sprocket bearing you need.

OEM number 37906-90, fits 1990 and later Harley Big Twins.

Made by Mid USA, this steel bearing is brand new, ready to roll, and includes the bearing itself—no extra fluff.

Solid quality, tight tolerances, and way easier than reusing the worn-out one.

If you’ve got the inner primary off, swap this in while you’re in there.

Peace of mind is cheap compared to a clutch that rattles or fails.

Don’t gamble with mystery bearings.

This one’s made to fit, made to last, and ready for the road.
