Product Description

The H&R 29378-1 Sport Lowering Springs are a suspension upgrade designed specifically for the 2000-2006 BMW X5 E53 equipped with rear air suspension. These specially tuned sport springs gently lower the SUV's ride height by approximately 1.2 in at the front and 1.0 in at the rear, reducing the center of gravity for improved stability and sharper handling without overly compromising everyday ride comfort. The progressive spring rate enhances cornering response and minimizes body roll for more confident driving dynamics.

Manufactured from high-tensile 54SiCr6 spring steel and finished with a corrosion-resistant powder coat, the 29378-1 springs offer durability and long-lasting performance. Designed to work with the air ride suspension system, this kit delivers an aggressive stance and improved road feel while maintaining balanced ride quality. Ideal for X5 owners who want better handling and a sportier appearance from their SUV, the H&R 29378-1 springs provide a direct fit solution tailored to the E53 platform.
