Suspension Kit

Product Overview

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. Easy, Bolt-In Installation Made in the USA Fitment Notes Engine mounts not included. QA1 offers several mounts for factory engines as well as popular engine swaps which are sold separately. For Fox Body: Kits for early year range Fox Bodies (1979-1986) will retain factory track width (narrow.) Kits for late year range Fox Bodies (1987-1993) will retain track width of the factory '87-'93 V8 cars (wide.) Not compatible with Cobra IRS
