Frequently Asked Questions
Can I adjust these shocks without special tools?
Yes — rebound damping, compression damping, and spring preload all adjust via accessible knobs and hand-threaded controls. No shop equipment needed.
What's the height adjustment range?
The adjustable eyelet provides 0.4 inches of height adjustment to fine-tune ride height and suspension geometry.
How does the monotube design improve performance?
The high-pressure gas monotube with deflective disc damping routes flow through two circuits, delivering consistent damping force throughout the shock stroke for better stability and control.
Will these shocks require revalving later?
Progressive 990 shocks are user-adjustable for High/Low speed compression, rebound, and preload — most riders dial in their setup without needing professional revalving.
