Steel Strut & Front Shock Adjustment Procedure

Printer Friendly Version Printer Friendly Version

    1. Set strut shock in vertical position
    2. Turn top adjustable 3/8" hex nut clockwise until nut stops.
    3. Turn top adjustable nut counter-clockwise 3 turns.
    4. If double adjustable, turn lower bump adjuster hex knob fully clockwise. Then turn out counter-clockwise 10 clicks.*
    5. Stroke strut shock 5 or 6 times to prime the valving and avoid cavitation (After laying horizontal the fluid is displaced).
    6. Turn top adjustable nut fully clockwise until nut stops again. At that position the strut shock is at it's full firm rebound (extension) position.
    7. Turn lower bump adjuster hex knob clockwise until it stops to bring it back to the full firm (compression) position.
    8. The strut shock is at it's softest position on extension when the top adjustable nut is turned 3 1/4 turns counterclockwise. O-ring damage could occur if turned any more than 3 1/4 turns.
    9. The strut shock is at it's softest on the bump (compression) when the adjuster hex knob is turned counter-clockwise until it stops.**

*Bump is same as a single adjustable shock at 10 clicks from full tight

**If trying to delay return of front weight transfer start at 6 clicks from full tight.
6 or 7 clicks is also a good tight adjustment to use for a car that wheelstands violently and may help save your headers.
