Calculate Number of Preload Turns

The rear shock spring preload is pre-set to the total load. It can be varied to suit your own personal comfort.

NOTE

To determine the motorcycle configuration for an FLS, FLSS, FLSTFB or FLSTFBS, check the configuration/calibration character stamped on the VIN. Refer to Identification → Vehicle Identification Number (VIN) → Harley-Davidson VIN Breakdown: 2017 Softail Models.

Identify the number of preload turns for the weight of the rider.
1. FLSTC, FLSTF, FLS (APC, AUS), FLSS (AUS), FLSTFB (HDI, ENG, IND, BRZ) FLSTFBS (HDI, ENG): Refer to Table 1.
2. FXSB, FLSTN, FLS (all except APC/AUS), FLSS (all except AUS), FLSTFB (all except HDI, ENG, IND, BRZ), FLSTFBS (all except HDI, ENG): Refer to Table 2.
Calculate the number of turns for the intended passenger and cargo.
Add the number of turns for the rider to the number of turns required for the total weight of the passenger and/or cargo.

Adjustment

NOTE

Adjust the shocks with the motorcycle resting on the jiffy stand.
Adjust both shocks the same number of turns.

See Figure 1. Hold the shaft with a wrench on the flats of the shock shaft (3) and loosen the jamnut (1).
Use the tangs of the SHOCK ADJUSTMENT SPANNER (Part Number:94448-82B) (4) in the holes (2) in the rear shock canister to turn the canister clockwise until it stops. This position is the minimum rider weight position.
Mark the face of the canister for reference.
Turn the canister counterclockwise the number of turns calculated for the total load.
Tighten the jamnut.
