Unlock maximum performance and adjustability for your classic Mustang with QA1’s Pro Coil System. Designed specifically for 1964–1966 Mustangs, this double adjustable coilover kit gives you total control over ride quality, stance, and handling. Featuring 10” coil springs with a 450 lb./in. spring rate, this setup is perfect for aggressive street performance and track-style handling. COMPLETE TUNING CONTROL QA1 double adjustable shocks provide independent rebound and compression adjustment, with 18 clicks each. This lets you precisely tune how your Mustang responds to bumps, body roll, and cornering forces. Whether you’re dialing in settings for cruising, carving corners, or competition driving, you’ll have full suspension control at your fingertips. CUSTOMIZABLE RIDE HEIGHT Achieve the stance you want with ride height adjustment from factory stock height down to 2” lower. Perfect for lowering your Mustang for a more aggressive look or fine-tuning ride height to match wheels, tires, or handling preferences. EASY BOLT-IN INSTALLATION No cutting. No welding.
