Upgrade your classic Mustang's suspension with QA1's Pro Coil System. Engineered for 1964-1966 Mustangs, this single adjustable coilover kit offers modern handling, ride quality, and stance adjustability in a straightforward, bolt-in package. Featuring a 10" coil spring with a 400 lb./in. rate, it's an excellent choice for restomods and street-driven cars that need sharper handling and improved control. MODERN HANDLING & CONTROL Factory suspension designs limit tuning and performance. QA1's single adjustable coilovers let you fine-tune rebound and compression together with 18 adjustment settings.

Whether you're keeping an original look or going for a lower stance, QA1 Pro Coils let you achieve the right height without sacrificing suspension geometry or drivability. EASY BOLT-IN INSTALLATION No welding or cutting required. QA1 designed this system as a direct bolt-in replacement that installs with basic hand tools, making it a perfect upgrade for DIY enthusiasts.
