What is the spring rate for this coil-over system?

This particular QA1 MD302 series coil-over kit comes with 600 lbs/in springs. This is a good starting point for many street and strip applications, but you may want to choose a different rate depending on your specific needs. QA1 offers other spring rates as options.

Are these shocks rebuildable?

Yes, these QA1 shocks are rebuildable and revalvable. This can be done by QA1 directly or by a QA1 authorized service center, which helps extend the service life of the shocks. Regular rebuilds can maintain optimal performance.

What adjustments can I make with the double-adjustable feature?

The double-adjustable feature allows you to independently adjust the compression and rebound damping of the shock. Compression damping controls the shock's resistance to compression, while rebound damping controls the speed at which the shock returns to its original length after being compressed. This allows for very fine tuning of the suspension.
