- Lock the surface gauge in this position.





2. With the surface gauge positioned on a flat, level surface, record the measurement of the surface gauge position (measurement 1).





3. Position the surface gauge on the same flat, level surface as used in Step 1 and adjust the gauge arm until the scriber point is located in the center of the shock absorber mounting bolt.
- Lock the surface gauge in this position.





4. With the surface gauge positioned on a flat, level surface, record the measurement of the surface gauge position (measurement 2).





5. Subtract measurement 2 from measurement 1 to obtain the front ride height.
