Coilover Spring 8in x 2.5in x 400lb

The Coilover Spring 8in x 2.5in x 400lb (Part Number 080-250-400) is a precision-engineered suspension component designed for coil-over applications requiring reliable, consistent spring performance. With an 8-inch length, 2.5-inch inner diameter, and 400 pounds-per-inch spring rate, this coil spring delivers the predictable load curve and durability needed in demanding suspension setups where ride control and load capacity are critical.

Manufactured from high-quality steel and finished with a durable black powder coat, this coil spring resists corrosion and abrasion from road salt, moisture, and vibration exposure. The 400 lb/in spring rate is well-suited for mid-range suspension applications—stiff enough to manage vehicle load and minimize unwanted deflection, yet compliant enough to absorb impacts without excessive harshness. The 2.5-inch ID allows compatibility with standard coil-over shock bodies, and the 8-inch free length fits typical vertical suspension travel requirements.

This spring is commonly used in off-road vehicles, motorsports platforms, and performance suspension builds where tuning spring stiffness is essential to handling response and load support. Buyers upgrading or replacing worn coil-over springs—whether for lifted truck applications, race car setups, or precision handling tuning—will find this specification a practical replacement or upgrade component when properly matched to vehicle weight and intended use.

At 3.01 lbs per unit, the spring ships with minimal dimensional profile (4.25 x 4.25 x 11.25 inches), making it easy to handle and install. Always verify coil-over housing compatibility and confirm the 400 lb/in rate matches your vehicle's suspension design before installation.
