QA1 HK01-FM01 Details

Transform the way your early Mustang drives with QA1’s Level 1 Full Vehicle Handling Kit. Designed specifically for 1964–1966 Mustangs, this all-in-one suspension package delivers modern handling, improved ride quality, and a more confident driving feel - all in a system engineered for straightforward installation.

MODERN HANDLING FOR CLASSIC PERFORMANCE

Factory springs and stamped control arms can’t deliver the precision or stability today’s performance drivers expect. QA1’s Level 1 system replaces those components with modern, performance-engineered parts that improve suspension geometry, reduce body roll, and make your Mustang feel more planted and predictable.

STRAIGHTFORWARD INSTALLATION

QA1 designed this kit to make modern performance attainable for any classic Mustang builder. The front suspension is a true bolt-in system, retaining the factory shock towers for a clean fit. The rear axle is controlled with QA1’s single adjustable shocks for simple adjustments to both compression and rebound simultaneously. Once installed, you’ll enjoy a significant improvement in handling and overall driving experience.
