QA1 Precision Products Coilover Adjustable Spring Lowering Kits

QA1 Precision Products has built a formidable reputation among performance enthusiasts by engineering suspension systems that bridge the gap between race-proven technology and street-friendly usability. Their Coilover Adjustable Spring Lowering Kits are a prime example of that philosophy — purpose-built packages that give builders, hot rodders, and track-day drivers a straightforward path to a dialed-in stance and tunable ride quality.

What Makes QA1’s Coilover Kits Stand Out

QA1’s Coilover Shock and Spring Packages offer a convenient, all-in-one pair of best-selling shocks and their corresponding springs, and also include spanner wrenches and thrust bearings to make ride height adjustments — ensuring you have everything needed to finish the job. That level of completeness removes the guesswork of sourcing compatible components separately and is a key reason enthusiasts gravitate toward these kits.

One of the most important decisions when selecting a QA1 coilover kit is choosing the right valving configuration. Single adjustable shocks adjust compression and rebound damping simultaneously from one adjustment knob — so every click of compression is also a click of rebound — while double adjustable shocks allow for independent adjustment of both compression and rebound damping from separate knobs. This provides greater overall adjustability and customization potential for drivers who want to fine-tune their setup for the track, the street, or anywhere in between.

Engineered for Performance, Built in the USA

Features like deflective disc valving, customizable compression and rebound, and lightweight aluminum construction have made QA1 shocks a top choice in the performance suspension industry. These same attributes carry over into their coilover lowering kits, which use a precision machined aluminum piston with PTFE piston band, a 5/8” centerless ground hard chrome plated solid piston rod, and a three-step sealing system — and are 100% dyno tested and serialized, as well as revalveable and rebuildable by the QA1 factory or authorized service centers.

With evenly spaced valving changes throughout the adjustment range, there are no jumps when adjusting between any two clicks — a detail that reflects QA1’s commitment to predictable, repeatable performance rather than vague “on/off” tuning.

Versatile Applications

QA1 engineers high-quality, performance suspension systems for muscle cars, classic trucks, and race cars. Their coilover lowering kits reflect this breadth, with configurations suited to a wide range of classic platforms. A QA1 lowering kit is a great choice for drivers who want a more aggressive stance without sacrificing ride quality, while QA1 coilovers give you the adjustability needed for precise height and damping control. Whether you’re building a weekend cruiser or a dedicated track car, these kits offer a proven foundation.
