H&R 28999-4 Sport Lowering Springs for 2009-2015 BMW 740Li F02 w/Self-Leveling

Vehicle Fitment

• 2009-2015 BMW 740Li (F02 - 3.0L I6 Turbo, RWD, Long Wheelbase) - with factory self-leveling rear suspension

Fitment Notes

• This kit is for the F02 740Li (long wheelbase) WITH factory self-leveling rear suspension ONLY - confirm by checking rear shock absorbers for hydraulic leveling lines or wiring
• NOT compatible with the standard-wheelbase F01 740i - use a separate H&R part number for that application
• NOT compatible with F02 models equipped with factory air suspension (as opposed to self-leveling hydraulic suspension)
• Kit includes 2 front lowering springs and 2 rear regulating rods/brackets for the self-leveling system - rear springs are not replaced; the self-leveling system is adjusted via the included brackets to achieve the correct rear drop
• Rear drop of 1.3 in. is achieved through the self-leveling system's automatic height adjustment in response to the included regulating rods - not by spring replacement
• Compatible with OEM shock absorbers and most aftermarket dampers sized for the F02 platform
• Lowering height may vary slightly on vehicles with optional factory suspension packages or equipment differences
• Professional installation and a post-installation alignment are strongly recommended

Features

• Lowers the front approximately 1.4 in. (35.5mm) via new front sport springs; the self-leveling rear suspension uses included regulating rods to achieve a matched 1.3 in. (33mm) rear drop
• Progressive spring rate design delivers a compliant initial feel that firms up progressively under load - maintaining the 7 Series' signature long-distance ride refinement while meaningfully reducing body roll
• Lowers the center of gravity for improved cornering stability and reduced body lean on both street and highway
• Reduces aerodynamic drag at speed with a lower, more streamlined ride height profile
• Engineered to work seamlessly with the F02's factory self-leveling suspension system - the rear self-leveling function continues to operate normally after installation
• Manufactured from H&R's proprietary (HF) 54SiCr6 high-strength spring steel, rated at 290,000 psi tensile strength for exceptional resilience and longevity
• Shot-peened surface treatment extends spring service life by over 200% compared to untreated springs
• Powder-coated finish provides durable corrosion resistance
• 100% engineered, manufactured, and tested in Germany to ISO 9001 certified standards; TUV approved

Product Description

The H&R Sport 28999-4 is a complete lowering kit engineered specifically for the 2009-2015 BMW 740Li (F02) equipped with factory self-leveling rear suspension. Unlike a standard 4-spring lowering kit, this set works with the F02 740Li's unique suspension architecture: two new front sport springs lower the front by approximately 1.4 inches, while two included rear regulating rods adjust the self-leveling system's target height to achieve a matched 1.3 inch rear drop. The result is a level, cohesive lowered stance all around - without replacing the rear springs or compromising the self-leveling system's continued function.

H&R's progressive spring rate design ensures the front springs begin with a supple initial compliance that firms up progressively under cornering load, preserving the 740Li's refined, comfortable character while delivering noticeably improved handling and reduced body roll. Built from H&R's 54SiCr6 high-strength spring steel, shot-peened for extended fatigue life, and powder-coated for long-term durability, this kit is manufactured entirely in Germany to ISO 9001 standards. Important: this kit is for the long-wheelbase F02 740Li with self-leveling suspension only - confirm your vehicle's rear suspension type before ordering.
