What is the benefit of having double adjustable shocks?

Double adjustable shocks allow you to independently adjust the compression and rebound damping. This allows fine-tuning of the suspension for different driving conditions and preferences. You can dial in the ride for street comfort or adjust for optimal performance on the track.

Are these shocks rebuildable?

Yes, these QA1 shocks are rebuildable and revalvable. You can send them back to QA1 or an authorized service center for maintenance and adjustments, which extends the life of the shocks.

What spring rate should I choose?

The best spring rate depends on your specific vehicle setup, weight distribution, and intended use. QA1 offers different spring rate options to suit various applications, from street driving to drag racing. Consider your vehicle's weight and intended use when selecting the appropriate spring rate.
