This QA1 coil-over system includes springs rated at 600 lbs/in. This rate is suitable for a range of street and strip applications, offering a balance between comfort and performance. If you're unsure, it's always best to consult with a suspension specialist to determine the ideal spring rate for your specific needs.

Are these shocks rebuildable?

Yes, the QA1 shocks in this kit are rebuildable and revalveable by the QA1 factory or QA1 authorized service centers. This allows you to maintain the shocks over time and customize the valving to suit your specific driving preferences or track conditions. Regular maintenance ensures optimal performance and extends the lifespan of your investment.

What type of maintenance is required for these coil-overs?

QA1 recommends regular inspection of the shocks and springs for any signs of damage or wear. Keep the shocks clean and free of debris to prevent premature wear of the seals and other components. Depending on your usage, you may need to rebuild the shocks periodically to maintain optimal performance.
