QA1 Level 2 Drag Racing Suspension Kit DK32-FMM4

Every great pass starts with a great launch. The QA1 Level 2 Drag Racing Suspension kit DK32-FMM4 is a full-vehicle handling package designed to help your car leave the line harder, hook up more consistently, and track straight all the way through the quarter mile. Built for drag strip use, it improves both straight-line stability and 60 ft. times, giving you a stronger foundation for every run.

Engineered for Small Block and LS-Powered Cars

QA1 developed the Level 2 drag racing program for average-weight vehicles with stock trim and small block or LS power. That makes this kit a practical upgrade for street/strip builds and weekend racers who want real improvement at the track without committing to a full custom chassis.

Across the Level 2 drag line, QA1 deliberately selected softer spring rates. The goal is to maximize stored energy for weight transfer, so more load shifts to the rear tires at launch and more of your engine’s power goes into the pavement instead of into wheel spin.

Why Upgrade Your Drag Suspension

Factory suspension is tuned for everyday comfort, not for the sudden weight transfer of a drag launch. Under hard acceleration, stock components can allow axle movement and inconsistent traction that cost you tenths at the line. A dedicated setup like the QA1 Level 2 kit gives the chassis a purpose-built foundation, helping the car launch with more predictable weight transfer and run straighter, which builds confidence pass after pass.

What’s Included in Kit DK32-FMM4

• Upper trailing arms and lower trailing arms
• Lower control arms in tubular steel with a black finish
• K-member
• Solid 1.000 in. (25.40 mm) black rear sway bar
• Mounting hardware

The kit is sold as a complete set, so you get the core chassis components in a single order instead of sourcing each piece separately.

Tubular Steel Construction

The control arms use a tubular steel design finished in black. Tubular construction provides a strong, rigid connection between the chassis and rear axle, helping keep suspension geometry consistent under the heavy loads of a hard launch. The black finish also gives the underside of your build a clean, finished look.

Easy Bolt-In Installation

QA1 designed these components for straightforward bolt-in installation. They work seamlessly with the OEM parts they attach to, so installation stays simple, and you can spend less time in the garage and more time at the track.

What’s Not Included

To plan your build properly, note that this kit does not include front or rear coil springs, leaf springs, front or rear shocks/struts, a front sway bar, end link, sway bar or leaf spring bushings, tie rod sleeves or ends, spindles, a panhard bar, a torque arm, upper control arms, brace or strut tower bars, subframe connectors, or brake components.

For heavily modified vehicles, QA1 drag racing suspension kits are available with or without shocks and struts. That gives you the flexibility to choose the spring rates and damping that match your build.
