Frequently Asked Questions

Will this fit my Harley Sportster?

No — this is for Big Twin models only. Sportster clutch baskets use a different bore and tooth pattern.

What year Harleys does this fit?

Big Twin models 1984 and newer, including FXEF, FXST, and related chassis.

Is this a direct bolt-in replacement?

Yes — the clutch basket and ring gear bolt directly onto your stock primary drive shaft with no modifications needed.

Do I need new clutch plates when I install this?

Not necessarily, but inspect your existing plates for wear. If they're glazed or damaged, replace them at the same time for best clutch performance.
