AIR SUSPENSION PUMP AND GAUGE
HD-34633
1

General
Refer to Table 1. The vehicle features air-adjustable rear suspension. Air pressure in the rear shocks may be adjusted to suit load requirements, riding style and personal comfort.
NOTE
These are recommended starting points. Adjust to suit load conditions, riding style and comfort desired. Less initial pressure does not necessarily result in a softer ride. Using pressures outside the recommended loading range will result in a reduction of available suspension travel and reduced rider comfort.

Adjusting Shock Pressure
NOTICE
Do not exceed maximum air pressure for suspension. Air components fill rapidly. Therefore, use low air line pressure. Failure to do so can result in possible damage to components. (00165b)
WARNING
Use caution when bleeding air from the suspension. Moisture combined with lubricant may leak onto the rear wheel, tire and/or brake components and adversely affect traction, which could result in death or serious injury. (00084a)
See Figure 1. To adjust the rear shock air pressure, use an air pump to fill or release air from the air valve located behind the right side cover.
NOTE
  • An AIR SUSPENSION PUMP AND GAUGE (Part Number:HD-34633) is available at your Harley-Davidson dealer.
  • Do not exceed maximum GVWR or GAWR.
  • Always clear the line by adding 21–35 kPa (3–5 psi) before releasing air from the pump's valve, but do not exceed 345 kPa (50 psi).
