Upgrade the handling and stance of your Infiniti G37 Coupe with the Swift Springs 4N906 Sport Suspension Spring Kit. Designed for 2009-2015 models, this complete spring set includes applications for both the front and rear suspension. The kit is engineered for drivers who want a more responsive street-driving experience, improved chassis control, and a sportier appearance while retaining the familiar functionality of the factory suspension system.
The Swift Springs Sport Springs are manufactured from durable steel and finished with a red powder coat for added protection against everyday environmental exposure. Their lowering design helps create a more performance-oriented profile and can reduce excessive body movement during cornering, acceleration, and braking. By optimizing spring performance at all four corners, the kit supports more balanced handling and a connected feel behind the wheel. Installation should be performed by a qualified technician, and a professional alignment is recommended after installation to help promote proper tire wear and suspension performance.
This Swift Springs suspension spring kit is a practical choice for Infiniti G37 Coupe owners seeking a focused upgrade for spirited driving, daily use, or appearance-focused builds. The application-specific design helps simplify component selection by providing a matched front and rear spring set for the intended vehicle platform. The durable construction and protective finish are suited to regular road use, while the sport-oriented tuning complements drivers looking for sharper handling without replacing the entire suspension system. Verify vehicle fitment before installation and follow all manufacturer and installer recommendations.
