Softail Frame / Driveline / Swingarms

What Is In This Collection

Frame, swingarm and final drive parts for the Softail - swingarms and frame hardware, frame stabilizers, kickstands, shift linkage, and the chains, drive belts, sprockets, pulleys and spacers that carry power to the rear wheel. What we list for the Softail moves as the brands we carry release more for the platform.

Softail Fitment

Softail covers '84-'17 - FXST, FLSTF Fat Boy, FLSTC Heritage, FXSTB Night Train, FLS Slim and FXSB Breakout. These are cable-throttle bikes. 2018 and up is the M8 Softail, a different platform - see M8 Softail Parts.

Years that change what fits:

• 2000 - the Softail took the Twin Cam, a year after Touring and Dyna.
• 2018 - the Milwaukee-Eight Softail replaced both the Softail and the Dyna on a new frame.

Worth Knowing

A frame stabilizer ties the swingarm pivot area more rigidly to the frame and takes flex out of the chassis under load - a common first upgrade before anyone touches the suspension. Chain and sprocket work is a matched set: pitch, link count and tooth count all have to agree, and changing final drive gearing changes your speedometer reading unless it is recalibrated.
