QA1 MOD Series Coil-Over Shock Absorber - Piggyback - Left Hand - Bearing Mount - 12.5in/18.75in

If you're building a high-performance drag car or a pro-touring machine, you know how crucial it is to adapt your suspension to changing track conditions. The QA1 MOD Series coil-over shock absorber is built for exactly that. This is a left-hand, piggyback-style shock with bearing mounts, designed for serious performance applications where fine-tuning is key. It offers a compressed length of 12.5 inches and extends to 18.75 inches, with 6.25 inches of travel.

What really sets this shock apart is its QuickTune Technology. This is a patent-pending system that lets you swap out the valve packs in minutes, without even removing the shock from your car. This means you can adjust compression and rebound settings without interrupting the oil flow or exposing the internals to dirt and air, which is a huge advantage when you need to make quick changes between runs or during testing. It comes standard with medium compression and rebound valve packs, and offers 4-way adjustability for both high and low-speed bleed.

This shock is 100% dyno tested and serialized, so you know you're getting a unit that's been checked for performance and consistency. It's also made right here in the USA. Because this is a high-performance component, we recommend consulting QA1's technical resources or a qualified suspension specialist to ensure proper installation and tuning for your specific vehicle and driving needs.
