QA1 Mustang Suspension Parts & Pro-Active Systems

Product images may differ from actual product appearance.

These QA1 suspension parts for Mustangs are some of the most advanced ever designed.

Coil-Over Conversion
The Coil-Over Conversion Kit only works with QA1 Mustang Struts, and it requires QA1's caster/camber plates (#122-CC100MU). Everything else is included to convert threaded struts to coil-overs. Kit contents:

Two 175lb springs

Two 2-piece upper spring caps with bearings

Two spring seats

Two spring seat jam nuts and washers
The Coil-Over Hardware Kit for two QA1 Mustang Struts includes spring caps, seats, and washers.

Eco-Comp Tubular Control Arms
Eco-Comp Tubular Control Arms are an economical choice for street and strip. They are built with QA1's exclusive compressed rubber bushings and engineered for performance.

Pro-Comp Tubular Control Arms
These control arms use QA1's exclusive heat-treated chromoly, Teflon/Kevlar-lined, XM Rodends. Spacers are included to allow forward and backward arm movement for wheelbase adjustment.

Tubular K-Members
Designed to reduce weight (up to 28 pounds), increase strength, improve geometry, and bolt-in as
a factory swap, QA1's Tubular K-Members' mounting points have been digitally indexed from new factory pieces. Other highlights include: greater header and oil pan clearances for easier installation and maintenance; improved bump steer, anti-dive, and Ackerman angles for maximum performance; black powdercoating for durability; and the use of stock or aftermarket A-arms. When using coil-over kits, the spring perches are removable for even more weight savings.

Pro-Active Systems
So, put all the parts together, and what do you get? QA1 Pro-Active Systems.
Offered with bushing or rodend-mounted control arms, each one-stop-shop system includes a coil-over conversion kit, struts, caster/camber plates, tubular control arms, and a tubular K-member.
