H&R 29439-1 Sport Lowering Springs Set - 1.5" Front / 1.4" Rear Drop

The H&R 29439-1 Sport Springs are H&R's number one selling lowering spring, delivering a perfect balance of improved handling, a lowered stance, and comfortable street-driven ride quality. Engineered and manufactured at H&R's ISO 9001 certified facility in Germany, these springs are built to exacting standards that enthusiasts trust.

Constructed from 54SiCr6 high-fatigue spring steel rated at 290,000 psi tensile strength, each spring is also shot-peened to extend service life by more than 200%. The result is a spring that will not set or sag over time, maintaining consistent ride height and performance for the life of the vehicle.

The progressive spring rate design allows the suspension to adapt fluidly to road conditions — compliant during everyday cruising, yet firm when cornering demands it. By lowering the vehicle's center of gravity, these springs reduce body roll and sharpen handling without introducing the harsh ride associated with lesser lowering spring designs. The reduced fender gap also gives the vehicle a cleaner, more aggressive appearance.
