GS401 Front Pro Coil Coilover Shock, Single Adjustable, GM, No Springs

QA1 Single Adjustable Pro-Coil shocks are an excellent choice to gain a better stance, ride quality and performance. These are a great solution for adjustable ride height, and the single-adjustable valving provides ample range of tunability for comfort and performance.
DIAL IN THE PERFECT STANCE
Achieving the perfect, level stance is critical for the overall look and appearance of your car. Pro-Coil shocks offer 2 inches of ride height adjustability, allowing you to dial in the perfect stance. Adjustments within this range can be made with a simple turn of the spring seat nut. For an additional drop beyond 2 inches, consider adding drop spindles to your car.
TUNE YOUR RIDE COMFORT & PERFORMANCE
QA1 single adjustable coilovers deliver exceptional ride quality and performance for your vehicle. With the simple turn of a dial, you can effortlessly switch between a comfortable cruise and a more aggressive feel, making them ideal for daily driving or twisty backroads. Accessing the 18-position knob is easy, and by turning the steering wheel to full lock, you can reach in and make your tuning adjustments at the base of the shock.
EASY, BOLT-IN INSTALLATION
Pro-Coil shocks seamlessly bolt-in with both Original Equipment (OE) stamped steel control arms or QA1 tubular control arms. This gives you the flexibility to use your existing setup or upgrade your control arms for additional performance gains.
