Completely Adjustable To Suit Any Track!

QA1 MOD Series Shocks are double-adjustable shock featuring two of QA1's patent-pending MOD Series Valve Packs; one for compression and one for rebound. Rather than having multiple shocks with different valving or finding a happy medium with one set, QA1 MOD Series Shocks allow you completely re-valve your shocks at the race track! 

Traditionally, your shock piston is going to have a set of shim stacks that set your valving from soft to firm, for both compression and rebound. This makes adapting to changes in track conditions, weather, and different courses complicated and expensive. Just by switching out one or both valve packs, QA1's MOD Series Valve Packs allow you to operate at different ranges from extremely stiff to extremely soft, giving you complete adaptability for anywhere, anytime!
