SWIFT SPRINGS 4H918R Swift Springs Spec-R Lowering Spring Kit 4H918R for 2017-2020 Honda Civic Sport and Si

Upgrade the handling and stance of your 2017-2020 Honda Civic Sport or Si with the Swift Springs Spec-R Lowering Spring Kit, part number 4H918R. Designed for enthusiasts seeking a more responsive driving experience, this application-specific suspension spring kit replaces the factory springs with performance-focused front and rear springs engineered for a lowered ride height and improved road presence.
The Swift Springs Spec-R kit is constructed from durable steel and finished with a black powder coat for added protection against everyday road exposure. Its application-specific design helps provide a proper fit for compatible Honda Civic models while supporting the vehicle’s suspension system during spirited street driving, cornering, and general performance use. The kit is intended for installation on both the front and rear of the vehicle, providing a balanced suspension upgrade rather than changing only one axle.
As a complete spring solution from Swift Springs, the 4H918R kit is a practical choice for drivers who want to enhance suspension performance without selecting individual springs separately. Lowering springs can help create a more purposeful appearance and may reduce body movement during acceleration, braking, and cornering when properly installed with compatible suspension components. Professional installation is recommended, followed by an alignment to help maintain proper handling and tire wear.
Verify vehicle trim and suspension compatibility before ordering. This Swift Springs Spec-R kit is designed for 2017-2020 Honda Civic Sport and Si applications and includes front and rear lowering springs. It does not include unrelated suspension hardware or installation services. Follow all manufacturer installation instructions and inspect surrounding suspension components during installation.
