Adjusting Suspension (High Performance Shocks)


Preload Adjustment

When to Adjust:

  • Front preload adjustment - increase preload if operating with front attachment or cab or under heavy load condition.

How to Adjust:

  1. Park machine safely (see Parking Safely in the SAFETY Section).

  2. Block rear tires.

  3. Raise the front of machine with a safe lifting device and lower machine onto jack stands or other stable support.

    Using a punch and hammer, loosen the upper jam nut (A) tightened against preload collar (B).


  5. Using the supplied spanner wrench for high performance shocks, securely engage the adjustable preload collar (B) on shock (C). Rotate preload collar to desired preload condition. The collar will stop rotating when maximum preload is achieved.

  6. Using a punch and hammer, tighten the upper jam nut against preload collar.

  7. Be sure both front shock preload collars are set to the same position. Be sure both rear shock preload collars are set to the same position.

    Repeat this operation on all shocks as needed.


Compression Adjustment

When to Adjust:

  • Front compression adjustment - Adjust the front compression adjustment to achieve optimum ride comfort for operating condition. Clockwise rotation provides a stiffer ride. Counter clockwise rotation provides a softer ride. Compression adjuster is a detent (clicks) adjustment. Count the number of clicks from one extreme of the adjustment range when making adjustments to know your position in the adjustable range.
  • Rear compression adjustment - Adjust the rear compression adjustment to achieve optimum ride comfort for operating condition or for heavy load compensation. Clockwise rotation provides a stiffer ride. Counter clockwise rotation provides a softer ride. Compression adjuster is a detent (clicks) adjustment. Count the clicks from one extreme of the adjustment range when making adjustments to know your position in the adjustable range.

How to Adjust:

  1. Park machine safely (see Parking Safely in the SAFETY Section).

  2. MXAL44301

    The compression adjuster is a blue colored knob (A) located on the remote reservoir (B) (attached to the shock by a steel braided hose).


  3. Grasp the blue knob and rotate to desired position.

  4. Be sure both compression adjustors are set to the same position.

    Repeat this operation on all shocks as needed.
