Product Details

QA1 Precision Products coil-over shocks combine a threaded-body adjustable shock with a coil spring in one assembly. They are designed for street performance, street rod, drag racing, autocross, and track applications. Each coilover shock (also called a coil-over shock absorber) lets you tune ride height and spring preload for improved handling and control.

Key Features:

  • Coil-over design combines the spring and shock into one assembly
  • Threaded body and adjustable spring perch for ride height and preload tuning
  • Adjustable damping on the Ultra Ride and adjustable models for tuning ride quality
  • Precision-machined, American-made construction from QA1
  • Corrosion-resistant finish for long service life
  • Eye-to-eye mounting designs for straightforward installation in many suspension setups

QA1 is well known for precision-engineered suspension components for performance and racing use. This product line offers a dependable way to improve handling, adjust stance, and refine ride quality. Specific compressed and extended lengths, spring rates, and mounting details vary by model, so check the individual part number you select.
