H&R 51851-88 Race Springs Lowering Coil Springs Set

H&R Sport Race Springs (Part# 51851-88) are engineered and manufactured at H&R's ISO 9001 certified facility in Lennestadt, Germany. Each spring is cold-wound from a proprietary 54SiCr6 silicon-chromium spring steel alloy, delivering a tensile strength rated at 290,000 psi — one of the highest in the industry — for exceptional durability and long-term resiliency.

H&R Race Springs are purpose-built for drivers who demand uncompromising, race-ready handling performance on the street or track. The aggressive spring rates provide a dramatically firmer, more responsive feel compared to stock springs, giving your vehicle a planted, confidence-inspiring stance and razor-sharp cornering capability.

Key Features:

• Manufactured from proprietary 54SiCr6 spring steel rated at 290,000 psi tensile strength
• Produced at H&R's ISO 9001 certified engineering and manufacturing facility in Germany
• Lowers ride height an average of 1.75 to 2.5 inches for an aggressive, race-inspired stance
• Designed for maximum cornering response, tight handling, and race-level performance
• Progressive or linear spring rates matched to OEM strut and shock geometry
• Each spring is shot-peened and powder-coated for corrosion resistance

Note: A camber correction device — such as H&R Triple C Camber Adjustment Bolts — may be required after installation to dial out excess negative camber, optimize tire wear, and extract peak handling performance from the lowered suspension geometry.
