Gas-a-Just Product Line

For rear suspension service on the Chrysler 300, Dodge Challenger, and Dodge Charger, SA1007 is calibrated to return the vehicle’s designed control characteristics without changing the factory suspension balance.

Detailed Description

KYB SA1007 is engineered for rear suspension replacement on the Chrysler 300, Dodge Challenger, and Dodge Charger. It is designed to restore ride control, lane-change response, stopping stability, and handling consistency by matching the vehicle’s original suspension calibration rather than altering it. The assembly uses OE-quality components and is produced on the same KYB lines that supply original equipment manufacturers, which supports consistent fit and damping performance for these rear applications. This part number SA1007 is a direct service choice for drivers replacing worn rear shocks on 2011-2023 Chrysler 300, 2011-2023 Dodge Challenger without Sport Suspension and without Electronic Suspension, and 2011-2023 Dodge Charger.

Common Problems This Part Addresses

• Excessive rear-end bounce after bumps
• Reduced stability during braking and lane changes
• Loose or unsettled handling from worn rear shocks
• Uneven ride control on Chrysler 300, Dodge Challenger, or Dodge Charger rear suspension
• Noise or poor damping performance from aging shock components

Installation Notes and Tips

Verify rear fitment by year, model, and suspension configuration before installation. This SA1007 application is listed for the rear position only, and the Dodge Challenger fitment excludes Sport Suspension and Electronic Suspension. Confirm compressed length, extended length, and mount types against the original part before service. Inspect surrounding suspension components, including mounts and bushings, for wear that could affect final ride quality.
