Front Coil Springs in Black with 588 lbf/in Spring Rate for Toyota 4Runner (2003–2024) - Pair

Old Man Emu engineers each coil spring to ensure accurate load handling and consistent suspension geometry. Rather than focusing solely on lift height, design emphasis is placed on improving vehicle control, reducing front-end dive, and maintaining composure under additional equipment weight.

Manufactured from micro-alloyed spring steel, each coil is precision-formed on computer-controlled mandrels for dimensional consistency. A double scragging process reduces internal stress, enhancing fatigue resistance and extending service life.

Spring geometry is calibrated to match intended vehicle use and front axle load requirements. Consistent coil spacing and controlled spring rate support stable handling while maintaining proper articulation and factory mounting compatibility.

A 588 lbf/in spring rate increases front-end support and reduces dive during braking and cornering. When paired with Old Man Emu MT64 or Nitrocharger Plus shock absorbers, the system operates as a unified suspension package for improved damping control.

Matte black powder coating protects against corrosion and environmental exposure. Material composition and manufacturing standards are engineered to minimize sag and maintain consistent ride height over long-term use.
