Description

The K-Tuned Swift Spec-R Lowering Springs are performance-oriented suspension components engineered specifically for the 2021+ Acura TLX Type S. Despite their performance focus, they are tuned to maintain a comfortable ride quality suitable for daily driving. Key specifications for the Spec-R springs include a front spring rate of 10.2 kgf/mm and a rear spring rate of 7.4 kgf/mm. This setup contributes to improved stability and responsiveness. The springs provide a consistent -1.0 inch drop at both the front and rear, visually lowering the vehicle's profile. Swift Springs USA, known for their advanced spring technology, engineered these components to offer an optimal balance between track-ready suspension performance and refined street drivability for the TLX Type S. Installation of lowering springs typically involves replacing the factory springs and may require professional alignment to ensure optimal performance and tire wear. Compatibility is precisely matched to the 2021 and newer Acura TLX Type S model.
