QA1's double adjustable shocks have 324 valving options, you can easily adjust your compression and rebound valving and get the hard-core performance you need. The dual knobs allow you to choose from 18 valving options that adjust both compression and rebound valving individually, allowing total suspension control in one easy-to-reach location.
Summary: I installed these on a dedicated HPDE track car using the recommended track/race settings on the damping adjusters. So far they are working very well. But note that they don't allow the use of a bump stop on the shaft nor do they allow the shock to be used to limit droop, otherwise it will void the warranty - I had to set up separate bump stops on the suspension to limit travel.
Cons: Can't be used to limit suspension travel.
Pros: Quality; Wide range of adjustability.
Yes, I recommend this product.
