Product Details

H&R Sport Springs are engineered and manufactured at H&R's ISO 9001 certified facility in Germany, ensuring world-class quality control from raw material to finished product. Every spring is produced from a proprietary 54SiCr6 spring steel alloy rated at an impressive 290,000 psi tensile strength, delivering unrivaled resiliency and long-term performance that outlasts lesser spring materials.

Designed for enthusiasts who demand both improved handling and a more aggressive stance, H&R Sport Springs deliver a lower ride height without the punishing harshness associated with budget spring kits. These springs are specifically engineered for street use, striking the ideal balance between spirited, responsive cornering and everyday comfort.

Key Features:

  • Lowers vehicle 1.5–2.0 inches on average for a sportier stance
  • Manufactured from proprietary 54SiCr6 high-tensile spring steel (290,000 psi rated)
  • Produced at an ISO 9001 certified engineering and manufacturing facility in Germany
  • Engineered specifically for street driving — improved handling without sacrificing ride comfort
  • Superior resiliency and fatigue resistance for long service life
  • Direct OEM replacement fitment — no cutting or modification required

H&R Sport Springs are an ideal upgrade for drivers seeking enhanced cornering control, reduced body roll, and a more planted, aggressive look. As a drop-in replacement for factory springs, installation is straightforward and compatible with OEM or aftermarket shock absorbers.

Inventory is easy to use and I was able to find what I was looking for with no problem at all. Not only that, Autoplicity had what I was looking for for the cheapest price I could find anywhere else. $50 cheaper than any store I walked into, and cheaper than any other web site i looked at.

Love the pay with Amazon feature. Unbelievably fast shipping, great pricing on product. Excellent communication through the process. I'll be back!
