1 7/8in ID Spring 100# 10in Tall

The 1 7/8in ID Spring 100# 10in Tall from HYPERCO is a precision coil-over suspension spring engineered for performance vehicles, race cars, and high-demand off-road applications where tuned spring rates are critical to handling dynamics. This individual spring delivers a consistent 100 lb/in spring rate and is designed to work as part of a complete coil-over suspension system or as a replacement component for existing setups. Builders and suspension technicians rely on HYPERCO springs for their repeatability, durability, and ability to dial in the exact vertical stiffness needed for specific vehicle weight and ride-height targets.

Manufactured from high-quality steel and finished in a protective blue powder coat, this spring features a 1.875-inch inner diameter, 10-inch total length, and a 100 lb/in spring constant that resists compression with measurable precision. The coil-over design allows the spring to nest over a damper body, enabling independent adjustment of spring preload and ride height through collar manipulation. HYPERCO's manufacturing tolerances ensure minimal variation between springs, critical when building matched pairs for front or rear axles where uneven spring rates would create handling imbalances or unpredictable weight transfer during acceleration, braking, or cornering.

This spring is ideal for street performance cars, track-focused builds, and competition vehicles where suspension geometry and load control demand precision engineering. It pairs seamlessly with adjustable coil-over kits from major manufacturers and is commonly used in motorsport applications including road racing, autocross, and rally competition. When ordering, confirm your vehicle's total spring rate requirement and whether this 100 lb/in rate suits your front or rear application—springs are sold individually, so paired setups require two units. The 2.03 lb weight and compact 4.45 x 4.25 x 13.2-inch package make shipping economical while maintaining the structural integrity necessary for high-load driving.
