QA1 HK42-GMF3 Level 2 Full Vehicle Handling Kit 82-92 GM F-Body

The QA1 HK42-GMF3 is a comprehensive Level 2 Full Vehicle Handling Kit engineered for 1982–1992 GM F-Body platforms. Designed for enthusiasts who demand both street composure and track-ready performance, this suspension kit delivers a significant step up in adjustability and chassis control over the factory setup. Whether you're building for autocross, track days, or spirited weekend drives, this bolt-in kit transforms your F-body's dynamics from the ground up.

Key Features:

• Double Adjustable Shocks & Struts – Replace non-adjustable factory units with QA1 double adjustable shocks and struts. A simple dial allows quick rebound and compression tuning to tailor ride quality for street or track conditions.
• QA1 Spring Sliders – Retain the factory inboard spring location while opening clearance for wider tires and increased negative camber. Preserves OEM suspension geometry while optimizing cornering grip and allowing easy ride height adjustment.
• Lightweight Tubular K-Member – Sheds over 30 lbs compared to the factory steel K-member. Accepts interchangeable engine mounts to support a wide range of engine swap packages.
• Ride Height Reduction – Coilover shocks combined with QA1 Spring Sliders allow ride height to be lowered up to 2 inches, improving stance and center of gravity for enhanced cornering performance.
• Adjustable Panhard Bar – Corrects rear axle placement after lowering or when running wider-than-stock tires, keeping the rear axle properly centered in the chassis.
• Adjustable Trailing Arms – Allow fine-tuning of wheelbase to properly center the wheel and tire in the fenders.
• QA1 Wonder Bar & Subframe Connectors – Dramatically stiffen the F-body unibody, reducing chassis flex and twist during aggressive cornering, acceleration, and braking for more accurate steering response.
• Strut Tower Braces – Included to provide additional front chassis rigidity.
• Fully Bolt-In Design – No cutting or welding required for installation. Straightforward fitment for DIY builds.
• Made in the USA – Manufactured in Lakeville, Minnesota.
• Limited Lifetime Warranty – QA1 shocks and struts are covered by a Limited Lifetime Warranty (registration required at QA1.net/Warranty).

Notes: Engine mounts are not included with this kit. A QA1 adjustable torque arm and transmission crossmember are recommended for maximum performance and drivetrain swap compatibility.

The HK42-GMF3 is part of QA1's three-tier handling system, allowing you to build your F-body's suspension in stages with guaranteed component compatibility at every level.
