H&R 50142-88 Race Springs Lowering Coil Spring Set

H&R part number 50142-88 Race Springs are engineered for drivers who demand uncompromising handling performance and a aggressive, race-ready stance. Manufactured at H&R's ISO 9001 certified facility in Germany, these springs are built to the same exacting standards that have made H&R a trusted name in performance suspension worldwide.

Every H&R Race Spring is cold-wound from a proprietary 54SiCr6 silicon-chromium spring steel, heat-treated and shot-peened to achieve a tensile strength rating of 290,000 psi. This process delivers exceptional fatigue resistance, long-term resiliency, and consistent spring rates over the life of the product — qualities critical for track and performance street use.

H&R Race Springs deliver an aggressive lowering drop of 1.75 to 2.5 inches on average, dramatically reducing ride height for improved aerodynamics, a lower center of gravity, and responsive, tight cornering behavior. The result is a vehicle that looks and handles like it belongs on the circuit.

Key Features:

• Average lowering of 1.75–2.5 inches for a race-ready stance
• Manufactured from 54SiCr6 silicon-chromium spring steel for superior tensile strength (290,000 psi)
• Produced at an ISO 9001 certified engineering and manufacturing facility in Germany
• Shot-peened and heat-treated for maximum fatigue resistance and long service life
• Designed for responsive, tight handling and race-inspired performance
• Drop-in replacement — no permanent modifications required

Note: Due to the aggressive lowering drop, a camber correction device such as H&R Triple C Camber Adjustment Bolts may be required to eliminate excess negative camber, preserve tire life, and optimize vehicle alignment geometry.
