Configurations Tailored to Your Driving Style

The 52346-S400 kit is available in two configurations:

Drag Kit

• Utilizes rod ends on both upper and lower control arms to enhance weight transfer and reduce deflection.
• Features a lighter spring rate for improved rear grip during hard launches.
• Offers a drop range of 0"-2".

Handling Kit

• Incorporates poly bushings on lower control arms for better cornering and reduced noise, vibration, and harshness (NVH).

• MOD Series shocks are recommended for maximum tunability and higher force curves.
• Gen 3 Hemi power steering pumps require a pressure reducer and the installation of a power steering cooler.
• This kit is not compatible with other QA1 tubular products designed for torsion bar suspension.
