Mustang Drag Racing K-Member

Hard Core Race Applications Only

QA1's tubular K-members are designed from the ground up for weight savings, improved geometry and as a bolt-in swap for the factory K-member.

  • Bolt-In Design
    All mounting points have been digitally indexed from new, factory K-members.
  • Mild Steel DOM Tubular Construction
  • Weight Savings
    Up to 28 lbs. lighter than the factory K-members with increased strength by design.
  • Increased Header Clearance
    Header and oil pan clearance maximized for easier maintenance and installation.
  • Modular Design for Versatility
    Spring perches are removeable for extra weight savings when using coil-over kits. Stock or aftermarket a-arms can be used.
  • Improved Geometry
    Bump steer, anti-drive and Ackerman angles have been improved for maximum performance. If the vehicle has been modified, there is a potential for tire to fender clearance issues. This k-member will change the vehicle's stance to a performance race stance.

For best results, QA1 control arms are strongly recommended.

Not for street use!

K-Member Braces for Mustangs

QA1 K-Member Braces are designed to stabilize the front suspension during hard cornering, allowing for improved control and handling. These braces reinforce the OEM cross member, also known as the K-Member, and help to keep the lower control arms from distorting during extreme conditions. They are currently the only braces on the market to feature an adjustable sleeve for fine tuning the preload.
