Frequently Asked Questions
Can I adjust the shock without special tools?
Yes — rebound, compression, and preload all adjust via hand-accessible knobs and threaded eyelet. No tools required for mid-ride tuning.
What ride height change is available?
The adjustable eyelet provides 0.4 inches of height range to dial in sag and ground clearance.
Will this fit my Dyna Super Glide?
This shock is engineered for Dyna 990 models. Verify your specific year and model before ordering, as Dyna evolution may require different shocks.
How do I set preload for my weight?
Hand-thread the spring perch until you achieve 25–30% sag when seated on the bike. Progressive's website offers a preload guide by rider weight.
