QA1 MS302-08700 Mustang II Front Coilover Conversion System 700 lb Single Adjustable

The QA1 MS302-08700 is a front coil-over conversion system engineered for Mustang II front suspensions, delivering performance-tuned handling for street rods and custom builds. This complete kit replaces the factory separate shock and spring combination with a purpose-built coilover unit, providing a cleaner, more capable front suspension setup.

At the heart of the system are QA1 MS302 single-adjustable Pro Coil shocks featuring lightweight aluminum construction and a fully threaded body design. The threaded shock body allows precise ride height adjustment, enabling builders to dial in the perfect stance or fine-tune front-end weight balance for superior handling. Each shock is paired with a matching 8MB700 tapered coil spring — an 8-inch free-length, 700 lb/in rate chrome silicon steel spring with a 3.5-inch upper I.D. and 2.5-inch lower I.D.

Key Features:

• Single-adjustable valving — compression and rebound tuning for street and performance use
• Lightweight aluminum shock bodies — MS302 Pro Coil series with 1/2 in. lower eyelet bushing
• 700 lb/in spring rate — suited for heavier street rod front-end builds (1,700+ lb front weight)
• 8-inch free length tapered coil springs — chrome-plated, cold wound, heat treated, and shot peened for strength and consistency
• Fully threaded shock body — adjustable ride height for stance and weight balance tuning
• 100% dyno tested and serialized — quality-verified before leaving QA1's Minnesota facility
• Rebuildable and revalveable — serviceable by QA1 or authorized service centers
• Bolt-in installation — direct coilover conversion, no cutting or fabrication required
• Sold as a pair — includes 2 coilover shocks and 2 coil springs
• Suitable for drag racing, street performance, autocross, road racing, and street rod applications

QA1 springs carry a lifetime guarantee to remain within 2% of their original free height and rate. The MS302-08700 kit is manufactured in the USA and backed by QA1's standard limited warranty on parts and workmanship.
