QA1 Promo Star-12-300 Kit Pro-Rear Coilover D-Adj. 3.25in

If you're looking to give your drag car, street performance vehicle, or street rod a serious upgrade in rear suspension control, this QA1 HD Pro Rear Coilover Conversion System is a solid option. This kit is designed to replace your stock rear shocks and springs with a fully adjustable coilover setup, giving you much finer control over your vehicle's ride height and damping characteristics. It’s a popular choice for builders who want to dial in their suspension for specific driving conditions, whether that's launching off the line or cruising down the street.

This particular kit features double adjustable coilovers, meaning you can independently tune both compression and rebound damping. This level of adjustability allows you to fine-tune how the rear suspension behaves under acceleration and deceleration, helping to manage weight transfer and improve traction. The springs included are rated at 300lb, and the system is designed to fit vehicles with a 3.25-inch axle diameter. QA1 also includes a 40-inch long weld-in tube to help you properly position the new coilovers on your chassis. Everything you need for the conversion, including all mounting hardware, is in the box, making it a well-thought-out DIY solution.

QA1 is known for making suspension components in the USA, and this kit is no exception. The double adjustable shocks offer a wide range of tuning possibilities, and the inclusion of springs and all necessary hardware makes this a comprehensive package for anyone serious about improving their vehicle's rear suspension performance and stance.
