Ride Height Drop

Designed to provide an aggressive street stance while maintaining practical suspension travel.

The even front and rear drop significantly reduces factory wheel gap while lowering the Civic’s center of gravity for improved handling and a cleaner appearance.

Progressive Spring Technology

TruHart uses a progressive-rate spring design that offers approximately 20% more stiffness than OEM springs. This provides comfortable ride quality during everyday driving while increasing spring resistance during hard cornering and braking.

Benefits include:

• Improved suspension response
• Reduced body roll
• Better steering feel
• Increased cornering confidence
• Comfortable daily driving
• Improved road holding

Premium 55 Chrome Silicon Spring Steel

Each TruHart spring is manufactured from premium 55 chrome silicon spring steel, providing excellent fatigue resistance and long-term durability.

Construction features include:

• Cold-wound 55 chrome silicon spring steel
• Precision-manufactured spring coils
• ISO 9001 certified production
• TÜV-approved manufacturing facility
• Corrosion-resistant finish
• Engineered to exceed OE standards

The advanced material helps resist premature sagging while maintaining consistent ride height over years of use.

Improve Civic Handling

Lowering your eighth-generation Civic provides significant improvements in vehicle dynamics.

Performance benefits include:

• Reduced body roll
• Lower center of gravity
• Faster steering response
• Improved cornering grip
• Reduced brake dive
• Reduced weight transfer
• Better high-speed stability
• Sportier overall appearance

Whether commuting, attending local meets, or enjoying mountain roads, the Civic feels more responsive and composed.

OEM and Aftermarket Shock Compatibility

TruHart lowering springs are engineered for use with:

• Factory Honda shocks
• OEM replacement dampers
• TruHart Sport Shocks
• Performance aftermarket shocks

While factory shocks may be reused if they remain in good condition, TruHart recommends pairing these springs with TruHart Sport Shocks for optimal ride quality and suspension control.

Daily Driver Comfort

Despite the aggressive ride height, these springs are engineered to maintain comfortable street manners.

Drivers can expect:

• Controlled ride quality
• Predictable suspension movement
• Reduced suspension float
• Improved chassis balance
• Comfortable highway driving

The progressive spring design helps absorb smaller road imperfections while increasing support during spirited driving.
