Aluminum Front Shock Adjustment Procedure Printer Friendly Version - Set strut shock in vertical position
- Turn top adjustable 3/8" hex nut clockwise until nut stops.
- Turn top adjustable nut counter-clockwise 3 turns.
- If double adjustable, turn lower bump adjuster hex knob fully clockwise. Then turn out counter-clockwise 10 clicks.*
- Stroke strut shock 5 or 6 times to prime the valving and avoid cavitation (After laying horizontal the fluid is displaced).
- 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.
- Turn lower bump adjuster hex knob clockwise until it stops to bring it back to the full firm (compression) position.
- 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.
- The strut shock is at it's softest on the bump (compression) when the adjuster hex knob is turned counter-clockwise till it stops.**
Baseline Setting for Struts and Front Shocks on Drag Radial Cars The following adjustments are based with all sweeps or clicks starting from a full tight adjustment (clockwise) position. Start the fronts set at 1 turn or 6 sweeps on the rebound adjustment and 6 clicks on the compression setting.
Aluminum Body Front Shock Baseline Settings Cars Horsepower | On Top (extension) | Bottom (compression) |
| 3000 HP | 1/2 turn | 12 clicks | 2500 HP | 3/4 turn | 12 clicks | 2000 HP | 1 turn | 10 clicks | 1500 HP | 1 1/2 turn | 8-9 clicks | 1000 HP | 2 turns | 8 clicks | 500 HP | 3 turns | 7 clicks |
*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.
