QA1 Coilovers, Shocks, Springs & Suspension Parts

What This Brand Covers

QA1 is a suspension manufacturer known for adjustable coilover systems, shock absorbers, and complete handling kits built for muscle cars, classic trucks, drag cars, and pro touring builds. The lineup covers everything from single component shock replacement to full vehicle handling packages.

Brand Focus

QA1 concentrates on American muscle car and classic truck platforms, with deep coverage of GM, Ford, and Mopar chassis rather than import applications.

Coilovers and Shocks

QA1 Pro coilover systems and Proma Star and Stocker Star shock absorbers are available in single and double adjustable configurations, letting builders dial in ride quality and handling response for street, strip, and track use.

Adjustability

Single adjustable shocks allow rebound tuning while double adjustable shocks allow independent control of compression and rebound, giving pro touring and drag racing builds a wider tuning range.

Handling Kits and Big Wheel Kits

Complete Level 1 and Level 2 handling kits combine shocks, springs, sway bars, and supporting hardware into a single package for classic GM B-Body and F-Body platforms. Big Wheel Kits raise ride height and clearance to accommodate larger wheel and tire packages on classic muscle cars.

Four Link and Conversion Systems

QA1 four link systems and coil over conversion kits let builders convert leaf spring rear suspensions on classic trucks like the Ford F100 to a coilover setup for improved ride and handling control.

Springs and Suspension Hardware

QA1 offers a wide range of coilover springs, tapered springs, and high travel springs in various lengths and spring rates, along with rod ends, linkage rods, tube adapters, and thrust bearing kits for building or servicing custom suspension setups.

Platform Coverage

QA1 supports the Ford Mustang and Ford F100, Chevrolet Camaro, Corvette, Chevelle, and Silverado, GM A-Body, B-Body, F-Body, G-Body, and X-Body platforms, and classic and modern muscle car and truck applications built for street, strip, and pro touring use.
