Product Overview

The QA1 Level 3 Handling Kit is a serious upgrade for people seeking ultimate handling and performance from their SN95 Mustang. The kit includes a lightweight tubular K-member, control arms, boxed trailing arms, sway bars, and front double adjustable coilovers and rear MOD Series 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. Paired with lightweight, high-travel springs with hand-selected rates perfect for flat cornering autocross and road race Mustangs.

These kits offer up to 2" lower than stock ride height adjustment to dial in the perfect stance.

MOD Series rear coilovers provide competition cars with an unmatched level of tunability and control.

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.
