Product Overview
The QA1 Level 2 Handling Kit is a serious upgrade for people seeking a better handling and performance from their Fox Body Mustang. The kit includes a lightweight tubular K-member, control arms, boxed trailing arms, sway bars, and front and rear double adjust coilovers.
Tubular Front K-member
These are designed to save weight and free up room in your engine bay. Weighing only 25lbs., it's 50% lighter than stock K-members and boasts improved geometry and durability. Interchangeable engine mounts, sold separately, offer flexibility for running factory or late model engines including Coyotes.
Inverted Front Struts and Rear Coil-Overs
Front struts feature an inverted cartridge design, large diameter shaft, and lightweight aluminum body for improved suspension performance. The lightweight, high-travel springs with proven spring rates are optimized for improved handling and street performance.
These kits offer up to 2" lower than stock ride height adjustment to dial in the perfect stance.
Double-adjustable rear coilovers are great for both street and track-day cars looking to further tune their rear suspension.
Lightweight Caster Camber Plates
Aluminum caster camber plates improve Mustang handling and performance. Lighter and sleeker than steel, they offer precision adjustment to fine-tune suspension geometry for optimal performance.
Tubular Control Arms, Trailing Arms and Rear Sway Bar
Tubular control arms, trailing arms, and sway bars solve flexing and bushing bind, allowing smoother suspension movement, reduced body roll, and better traction in the corners.
Easy, Bolt-In Installation
Our commitment to thoughtful product design is evident in every fully bolt-in kit we produce, to deliver the highest level of performance, while ensuring trouble-free compatibility.
Made in the USA
QA1 struts, coilover shocks, and tubular suspension is proudly made in Lakeville, Minnesota.
