What does 'low-speed bleed' mean?

Low-speed bleed refers to the shock's ability to control movement during slow suspension changes, like cornering or braking. Adjusting this bleed allows you to fine-tune how the car responds to these inputs, improving handling and stability. With independent control over compression and rebound, you can dial in the perfect balance for your driving style.

What are the benefits of a nitrogen-charged canister?

A nitrogen-charged canister helps maintain consistent shock performance by preventing cavitation (formation of air bubbles) in the oil. This keeps the damping force consistent, even during hard use. The canister can be mounted piggyback or remotely, depending on space.

What spring rate should I choose?

The 750 lbs/in spring rate is a good starting point for many GM applications, but the ideal rate depends on your vehicle's weight, intended use, and personal preferences. Consider factors like engine weight, vehicle setup, and desired ride quality when selecting a spring rate. If you're unsure, consult a suspension specialist.

Product Details

soft or firm compression and rebound valve packs also available. Once the desired valving is in place, the unique double adjustable design, with adjustable low-speed bleed, allows for fully independent control over the compression and rebound characteristics. With all these adjustability options, the MOD Series shock achieves an expansive force curve capability and an unprecedented level of tunability. The shock also features mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas, and the base eyelet is indexable, so you can unbolt it and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, the MOD Series shock is 100% dyno tested and serialized and proudly made in QA1's Lakeville, Minnesota facility.
