Product Details

The QA1 Pro-Rear Coilover Shock Assembly Kit line is a rear coil-over conversion system. It replaces a factory rear shock and spring setup with adjustable QA1 coilover shocks and springs. Use it to improve stance, ride quality and handling on street, strip and track vehicles. It is also sold as a rear coilover kit, rear coil-over conversion kit or rear Pro Coil shock system.

Key Features:

  • Adjustable ride height: Threaded aluminum shock bodies and adjustable mounting brackets let you set the stance you want.
  • Tunable damping: Single-adjustable and double-adjustable shock options let you fine-tune ride and handling.
  • Complete hardware: Kits are designed to include the brackets, springs, shocks and mounting hardware needed for installation.
  • Bolt-in and weld-in designs: Many kits bolt in. Heavy-duty axle-mount kits use weld-on brackets.
  • Quality construction: QA1 coilovers are rebuildable and revalveable by QA1 or its authorized service centers. QA1 states they are dyno tested, serialized and made in the USA.
  • Warranty: QA1 double-adjustable shocks are eligible for a Limited Lifetime Warranty.

QA1 is known for precision suspension components. This line suits builders who want a clean, fully engineered rear coilover upgrade with a wide range of spring rates and shock valving options.
