18in Coil Over Spring High Travel

The 18in Coil Over Spring High Travel suspension component is engineered for serious off-road and performance driving applications where extended suspension articulation and load handling are critical. This coil-over spring is designed for builders and enthusiasts who demand maximum wheel travel, whether tackling challenging terrain, competing in off-road events, or building custom lifted platforms. High-travel coil-overs provide the damping control and spring rate consistency that aftermarket suspensions require when pushing vehicle geometry and ride height to the limit.

This 18-inch coil-over spring delivers progressive spring rates and extended compression travel, allowing the suspension to absorb large bumps and maintain tire contact during aggressive articulation. The compact cylindrical form factor (4.7 x 4.6 inches) fits within tight spring perches common to coil-over conversion kits and custom fabricated suspensions. Weighing 6.55 pounds, the spring maintains structural integrity under repeated cycling while the high-travel design accommodates both static load and dynamic suspension movement without bottoming out prematurely, a critical factor when running lifted vehicles or tackling washboard terrain at speed.

Mechanics and fabricators building independent suspension systems, rock crawlers, or lifted truck platforms will find this spring ideal for modular coil-over assemblies paired with monotube or twin-tube dampers. The 18-inch length accommodates mid-travel and long-travel suspension geometries common in modern off-road conversions. Always verify spring rate compatibility with your specific shock absorber and vehicle weight distribution before installation; matching spring and damper characteristics ensures responsive handling and prevents harsh bottoming or excessive droop during extended articulation events.
