1 7/8in ID Spring 125# 10in Tall

The 1 7/8in ID Spring 125# 10in Tall is a precision coil spring engineered for suspension tuning and chassis geometry modification in performance vehicles. This spring delivers a 125-pound rate per inch of compression, making it ideal for builders seeking refined ride control, reduced body roll, and improved handling characteristics during aggressive driving or track use. Whether you're dialing in a lowered stance, upgrading a factory suspension, or building a dedicated race platform, this spring provides the consistent load-bearing geometry necessary to maintain predictable vehicle dynamics across varied driving conditions.

This coil spring features a 1 7/8-inch inner diameter bore with a 10-inch free height and medium 125-pound spring rate that balances comfort with control—stiff enough to minimize suspension travel and squat under acceleration, yet compliant enough for daily street manners when paired with appropriately valved dampers. The compact 10-inch profile suits modern double-wishbone, multi-link, and independent rear suspension architectures common in contemporary performance builds. Weighing 1.85 pounds, the spring minimizes unsprung mass while delivering consistent preload characteristics, making it particularly valuable in front-end applications where reduced weight improves braking response and steering feedback.

Mechanics and chassis engineers favor this spring specification for professional suspension overhauls, custom fabrication projects, and vehicles requiring matched spring pairs for balanced geometry. It integrates seamlessly with aftermarket shock absorbers, coilover kits, and adjustable suspension platforms, though proper dampening selection and alignment verification remain critical after installation. The 125-pound rate works across a broad range of vehicle weights and intended use—from lightweight sports cars to mid-size sedans undergoing performance modification—provided suspension geometry is maintained and bump stops are correctly positioned to prevent coil binding.
