Product Description

The Eibach 1000.300.0300S coilover spring is engineered for high-travel off-road and performance applications where long suspension travel and consistent support are priorities. With a **300 lbs per inch** spring rate, **3.00 in inside diameter**, and **10.00 in free length**, this spring delivers compliant support while maintaining excellent articulation across rough terrain, making it well-suited for rally, desert, or extreme off-road builds.

Constructed from precision-formed high-tensile spring steel and finished in a rugged silver powder coat, the 1000.300.0300S offers enhanced resistance to corrosion and abrasion under demanding conditions. Its generous free length and optimized block height help improve wheel control, traction, and ride comfort during dynamic off-road use. Because this part is universal - not tied to a specific vehicle - verify compatibility with your coilover shock absorbers and suspension hardware before installation to ensure optimal performance.
