Product Details
The QA1 MOD Series coil-over shock absorber features a unique dry modular valve pack system, allowing you to quickly and easily revalve the shock without opening the main body. This means you can adjust the damping characteristics without introducing contaminants like dirt or air, which is crucial for maintaining consistent performance. This right-hand specific unit is designed for a bearing mount setup, offering a compressed height of 10.63 inches and an extended height of 15 inches, with 4.38 inches of travel.
This shock absorber is built with 4-way adjustability, giving you control over both high-speed and low-speed compression and rebound. The piggyback canister design is a notable feature, providing additional fluid capacity and allowing for more precise tuning of the damping. Each shock is 100% dyno tested and serialized to ensure it meets QA1's strict performance standards before it even leaves the factory. Being made in the USA, you can expect solid construction and attention to detail.
For those looking to fine-tune their suspension, the ability to swap out the QuickTune valve packs is a significant advantage. This allows for a wide range of adjustability to suit different driving conditions or preferences. The eye-to-eye mounting with bushings at both ends simplifies installation on many custom applications, though you'll want to confirm compatibility with your specific vehicle setup.
