[More Info]

Fit up to 28” wheels on your Caprice or Impala with a complete bolt-in suspension system. It has everything you need to get your Donk sitting right while giving you a better ride.

Single-Adjustable Coil-Overs

Adjustable coil-overs allow you dial in the exact look you want in minutes. Easily raise or lower your car up to 2” in the front, and set a custom rear ride height anywhere from stock height to up to 5" of drop. No more spacers or on-again, off-again installs. The included aluminum spanner wrenches allow you to set the exact squat you want with the full kit installed on your car. Single adjustable valving allows your to firm up or soften the ride with the simple twist of a knob.

Adjustable Upper and Lower Trailing Arms

Get your wheel and tire package to fit with adjustable trailing arms that center your rear axle in the wheel well. This gives you more clearance for up to 28” wheels.

EASY, BOLT-IN INSTALLATION

Parts come powder coated and ready to install with all necessary hardware. We put in extra hours in the R&D shop to make sure there's no cutting, grinding or welding required. Bolt the kit on right in your garage or work with your local shop.

FITMENT NOTES

  • Kits work with factory housings or Quick Performance 9” rear axles
