H&R 23009-1 VTF Adjustable Lowering Springs with Micro-Adjustable Perches

The H&R 23009-1 VTF Adjustable Lowering Springs deliver the ideal combination of lowering flexibility and factory-quality ride comfort. VTF stands for Verstellbar Tieferlegungs Federn — German for "adjustable lowering springs" — and represents H&R's premium solution for vehicles equipped with factory electronic or adaptive damping systems.

Unlike conventional fixed-height lowering springs, the VTF system features application-specific engineered adjustment collars and spring perches that allow fine-tuning of ride height down to the micro-millimeter. This gives you the ability to dial in your exact preferred stance without sacrificing the OEM electronic shock integration your vehicle relies on.

Key Features:

• Adjustable lowering range: approximately 0.60" – 1.40" front and 0.80" – 1.60" rear
• Fully compatible with factory electronic/adaptive shock absorbers — no aftermarket dampers required
• Precision micro-millimeter height adjustment via engineered collars and perches
• Progressively rate-tuned springs reduce body roll and improve balance and handling
• Manufactured from lightweight, high tensile strength spring steel alloy
• 100% made in Germany to ISO quality standards
• TÜV approved for safety and engineering compliance
• Backed by H&R's limited lifetime warranty

H&R VTF springs are engineered to work seamlessly with your vehicle's factory damping system, preserving OEM ride quality while noticeably reducing body roll and improving overall chassis balance. Whether you're looking for a subtle drop or a more aggressive stance, the VTF system lets you achieve it with precision. Part number 23009-1 is the front spring set in the VTF application.
