Racing shock manufacturers...
Racing shock manufacturers offer dyno measurements of their products. Take advantage of this service to keep your shock package optimum.
Q: If I have a shock that's leaking a little, how low can it get on fluid before it goes bad?
Workman: If you have a leaking shock, it's already bad.
Q: Is it cost effective to repair a crashed shock?
Workman: As long as the body of the shock is salvageable, it's usually cost effective to repair the shock.
Q: When I have the option (per track rules) should I use steel- or aluminum-body shocks?
Workman: Aluminum shocks are the way to go. They are repairable, which makes them less expensive in the long run. Aluminum shocks also run cooler than steel shocks, making them better from green to checker.
Q: Should I run shock covers?
Workman: No. Heat is the enemy, and shock covers trap heat.
Q: If I convert between gas pressure and twin-tube shocks do I need to change springs?
Workman: It will depend upon the rod pressure in the gas-pressure shocks. Different shock manufacturers use varying amounts of gas pressure in their shocks. Consult your shock manufacturer to determine if the rod pressure warrants a spring change.
Q: How much shock shaft should I have showing at ride height?
Workman: No less than 311/42 inches is a good rule of thumb.
Q: If the paint has been rubbed off the shock by the tire in tight mounting quarters, is this shock damaged?
Workman: If the shock is a gas-cell, twin-tube design, the odds are good the cell has already melted and ruptured due to the heat generated. If it is a gas-pressure, monotube shock it will last a little longer. Continually boiling the fluid will always lead to premature shock failure. Correct the mountings to keep the tire from rubbing the shock.
Q: Is it OK to mix brands of shocks on my race car?
Workman: Each manufacturer has a slightly different code system [specifying rates]. Though they are generally close, it is recommended you stick with one brand for consistency.
Q: Do I need adjustable shocks?
Workman: If you are a traveling racer, they are a must. Whatever the track conditions you find, you can tailor the shocks to fit. If you always run the same track, get one for the front and one for the back.
Q: If I'm getting wheelhop, is it a shock problem?
Workman: Wheelhop is often caused by using a shock that's too soft. Also, a severely worn shock will cause the problem.
