1 7/8in ID Spring 325# 10in Tall

The HYPERCO 1 7/8in ID Spring 325# 10in Tall (part number 1810D0325) is a high-performance coil-over suspension spring engineered for custom vehicle builds, off-road applications, and motorsport setups. With a 325 lb/in spring rate and 10-inch length, this spring delivers precise load handling and responsive suspension geometry tuning for drivers who demand exact spring characteristics in their suspension systems.

Specification details: 1.875-inch inner diameter accommodates standard coil-over shock bodies, 10-inch length integrates into compact and full-size suspension packages, and 325 lb/in spring rate provides moderate-to-stiff resistance suitable for both street and track use. The steel construction features a durable blue powder-coat finish that resists corrosion and UV degradation. Weighing 3.13 pounds, the spring maintains structural integrity under repeated compression cycles while remaining lightweight for suspension optimization. The compact 3.3 x 3.3 x 11.9 inch footprint ensures straightforward installation in confined chassis spaces.

This spring suits builders working with coil-over kits, street rod shops, off-road suspension designers, and performance tuners who require a known, consistent spring rate for vehicle dynamics calculations. The 325 lb/in rate sits in the mid-range of common performance applications—firm enough for controlled body roll and responsive handling, yet manageable for daily-use vehicles. Individual spring selection allows precise tuning without committing to complete pre-assembled kits, making it ideal for phased builds and custom suspension geometry work.

HYPERCO is recognized in the suspension industry for manufacturing springs to tight tolerances and consistent specifications. The 1810D0325 model integrates into established coil-over platforms and pairs with compatible shock absorbers and mounting hardware available through suspension specialists and performance retailers.
