Product Details

H&R Race Springs (PN 51655-88) are engineered for drivers who demand uncompromising handling and aggressive stance. Manufactured at H&R's ISO 9001 certified facility in Germany, every spring is cold-wound from a proprietary 54SiCr6 silicon-chrome spring steel rated at an exceptional 290,000 PSI tensile strength, delivering superior resiliency and fatigue resistance compared to conventional spring steel.

H&R Race Springs are purpose-built for track-focused performance and race-inspired aesthetics. The progressive spring rates provide a dramatic reduction in ride height while sharpening steering response and reducing body roll — exactly what's needed for spirited street driving or weekend track use.

Key Features:

  • Lowering drop: Approximately 1.75–2.5 inches average ride height reduction
  • Material: Proprietary 54SiCr6 silicon-chrome spring steel — 290,000 PSI tensile strength
  • Manufacturing: Produced at H&R's ISO 9001 certified engineering facility in Germany
  • Performance focus: Designed for race-ready handling with tight, responsive cornering feel
  • Finish: Corrosion-resistant powder coat finish for long-term durability
  • Direct fitment: Drop-in replacement for OEM springs — no cutting or modification required

Note: Due to the aggressive lowering drop, a camber correction solution such as H&R Triple C Camber Adjustment Bolts may be required to restore proper alignment geometry, maximize tire life, and optimize handling performance after installation.

Great Price fast shipping, I can't complain.

Very happy

Great transaction. The bike rack was about $90 less than a local retailer, and shipping was faster than promised. I wish all internet retailers were this reliable and useful.

It was easy to order and the truck bed extender we bought was the lowest price we could find! However, the shipping charge was higher than what was posted on the comparison sight. Nevertheless, it still came in under the next highest price from a different vendor.

I have had excellent service from this site and speedy delivery. They also send you an email with order info and tracking number everytime.

Fast service, great prices, highly recomended retailer.
