Coilover Spring 8in x 2.5in x 300lb

The SWIFT SPRINGS Coilover Spring 8in x 2.5in x 300lb (part number 080-250-300) is a precision coil-over suspension component designed for vehicles requiring custom spring rates and ride height adjustment. With an 8-inch length, 2.5-inch inner diameter, and 300 pounds-per-inch spring rate, this coilover spring delivers the stiffness needed for performance tuning, off-road recovery applications, and vehicles running aftermarket suspension systems. The black powder-coated steel construction resists corrosion while maintaining structural integrity under repeated compression cycles.

The 300 lb/in spring rate is a medium-stiff specification suitable for vehicles weighing 3,000–4,500 lbs per corner, depending on suspension geometry and ride height target. The 8-inch compressed length accommodates most coilover kits with standard ride-height range, while the 2.5-inch inner diameter ensures compatibility with standard coilover bodies and damper shafts. Steel construction with powder-coat finishing provides durability in both street and off-road environments. This is a single spring; coilover applications typically require matched pairs or sets for balanced suspension geometry.

This spring is engineered for buyers building or maintaining custom suspension systems—whether upgrading a street vehicle to lower ride height, replacing worn springs in an off-road recovery rig, or fine-tuning a performance build. Users should verify spring rate compatibility with their vehicle's total weight and suspension design before installation. The powder-coated finish protects against moisture and salt spray, important for vehicles operating in challenging environments.

Coilover springs are a core component of modern performance and off-road suspension systems. The 300 lb/in rate sits in the medium range, stiffer than stock springs on most vehicles but not as extreme as dedicated track-only setups. Buyers should confirm their coilover kit's specifications match this spring's inner diameter and compressed length before purchase.
