What does 'dyno tested' mean?

QA1 dyno tests each MOD Series shock to ensure it performs to spec. A dynamometer measures force and motion, so QA1 can verify the shock's damping characteristics before it ships. This helps ensure consistent performance.

What does 'adjustable low-speed bleed' mean?

Low-speed bleed refers to the shock's ability to control small, slow movements. This adjustment lets you fine-tune how the suspension reacts to body roll, braking, and small road imperfections. With independent control over compression and rebound, you can dial in the handling you want.

What other options are available for this coil-over system?

Soft or firm compression and rebound valve packs are also available. This allows you to further customize the valving to your specific needs. Refer to the manufacturer's documentation for available options and compatibility.
