H&R RF120-36-032.5 Race Spring 36mm ID 120N/mm Linear Rate

The H&R RF120-36-032.5 is a high-performance linear-rate race spring designed for motorsport and performance street applications. Engineered with a 36mm inner diameter and a spring rate of 120 N/mm, this spring is built to deliver consistent, predictable handling characteristics under demanding track conditions.

H&R race springs are manufactured in Germany to strict tolerances using high-tensile chrome-silicon steel wire, ensuring long service life and resistance to fatigue even under repeated high-load cycles. The linear rate design provides a smooth, progressive feel that is favored by motorsport engineers for its calculable and repeatable performance.

Key Features:

• Spring Rate: 120 N/mm (linear)
• Inner Diameter (ID): 36mm
• Free Length: 325mm (32.5 cm)
• Construction: High-tensile chrome-silicon steel wire
• Finish: H&R signature yellow powder coat for corrosion resistance
