Ride Height Drop

Designed to reduce factory rake while maintaining comfortable daily drivability.

The larger rear drop levels the vehicle’s factory stance while lowering the center of gravity for improved handling and a more athletic appearance.

Progressive Spring Technology

D2 PRO lowering springs feature a progressive-rate spring design that increases resistance as the suspension compresses.

Benefits include:

• Comfortable ride during normal driving
• Improved cornering stability
• Reduced body roll
• Better steering response
• Improved braking stability
• Reduced weight transfer
• Greater suspension control during aggressive driving

This progressive design provides excellent comfort during daily use while delivering additional support during spirited driving.

Premium 55 Chrome Silicon Spring Steel

Each D2 PRO spring is manufactured from 55 chrome silicon spring steel, offering exceptional fatigue resistance and structural strength.

Construction highlights include:

• 55 chrome silicon spring steel
• Precision cold-wound manufacturing
• Heat-treated construction
• Corrosion-resistant finish
• ISO 9001 quality-controlled production
• TÜV-approved manufacturing

These manufacturing standards help prevent premature spring sag while maintaining consistent ride height throughout years of service.
