Product Details

The QA1 Proma Star Double Adjustable Coilover Shock line gives hot rods, restomods, custom chassis builds and performance street or track cars a coilover shock with adjustable ride height and adjustable damping. It suits custom suspension setups where a direct-fit coilover isn't available.

Key Features:

  • Double-adjustable valving: Compression and rebound are tuned independently, so you can set up the handling and ride comfort you want for street, strip or track use.
  • Adjustable ride height: Turning the spring seat nut changes ride height, which helps you get a level stance.
  • Multiple mounting configurations: Bearing mount and bushing mount versions are offered, in a range of compressed and extended lengths.
  • Spring hardware included: The coilover hardware needed to mount your spring comes with the shock. You add a 2-1/2 inch I.D. coil spring in the rate and length you need.
  • Flexible installation: The shocks can be mounted body up or body down.
  • Made in the USA: QA1 builds Proma Star shocks in Lakeville, Minnesota.
  • Limited Lifetime Warranty: Proma Star shocks are eligible for QA1's Limited Lifetime Warranty.

A spanner wrench (QA1 P/N T114W or T115W) is required to adjust ride height and is sold separately. An optional thrust bearing kit (P/N 7888-109) is also sold separately.

QA1 is a well-known maker of performance suspension components. Proma Star coilover shocks are a good choice for builders who want adjustable damping and ride height from one shock.
