* Load: How much weight is in the car? More weight requires higher pressure. Are you carrying passengers, cargo, or towing?
* Desired Ride Height: Do you want a stiffer, higher ride, or a softer, lower ride?
* Shock Type and Condition: Different air shocks have different pressure ranges. The condition of the shocks themselves also affects performance. Worn shocks might need higher pressure to compensate.
* Manufacturer's Recommendations: If you know the *specific make and model* of air shocks installed, check their packaging or website for recommended pressure ranges.
Instead of searching for a magic number, I strongly advise this process:
1. Identify your air shocks: Find the brand and model number stamped on the shocks themselves.
2. Consult the manufacturer's instructions: This is the best source of information for pressure recommendations. Their website, or the packaging if you still have it, should specify a range.
3. Start low: Begin with the lowest pressure recommended by the manufacturer.
4. Adjust gradually: Add air in small increments (e.g., 5 PSI at a time), checking the ride height and firmness after each adjustment.
5. Find your sweet spot: Adjust until you achieve the desired ride height and handling characteristics. Consider the load your Nova typically carries.
Important Note: Over-inflating air shocks can severely damage them and other suspension components. Always stay within the manufacturer's recommended pressure range. If you're unsure, consult a qualified mechanic.
