QA1 DDR3855 Proma Star Double Adjustable Shock

Every QA1 double adjustable shock features 24 positions of compression adjustment and 24 positions of rebound adjustment, providing 576 possible combinations to maximize the performance of your vehicle. There are three features that are critical for an excellent double adjustable:
1. Adjustment range
QA1's adjustment range encompasses virtually every application.
2.Tuning ability within the adjustment range QA1 offers evenly spaced valving changes throughout the adjustment range. There are no "jumps" when adjusting
between any two clicks.
3. Independence of compression & rebound adjustments
QA1 has developed a truly independent double adjustable shock. When the compression knob is adjusted, rebound does not change and vice versa. Compression and rebound are controlled independently, allowing the ultimate in fine-tuning for any application. Most manufacturers of double adjustables make this same claim - however, they cannot necessarily back it up with the product. We strongly encourage serious racers and performance enthusiasts to put their double adjustables to the test on a dyno. We are confident that you will find that there is no comparison between QA1 and the competition.
