Old Man Emu Front Coil Springs in Black with 590 lbf/in Spring Rate for Toyota 4Runner (2003–2024) - Pair

Old Man Emu suspension systems are engineered to support remote travel where vehicles carry additional fuel, recovery gear, and survival equipment. Rather than focusing solely on lift height, design philosophy emphasizes maintaining vehicle control and improving ride composure under heavy payload conditions.

Each coil spring is manufactured from micro-alloyed spring steel for improved fatigue resistance and long-term durability. Springs are double scragged to reduce internal stress and improve structural longevity during repeated compression cycles.

Computer-precision mandrel forming ensures each coil maintains exact dimensional tolerances for consistent performance and proper vehicle fitment. Variable rate coil design allows progressive spring response under changing load conditions.

A 590 lbf/in spring rate enhances front suspension stability during braking, cornering, and rough terrain travel. Performance gains are most noticeable when the vehicle is carrying expedition cargo or aftermarket equipment.

Hard wearing black powder coat finish protects against corrosion, debris impact, and environmental exposure. High-grade manufacturing processes are used to reduce sagging and maintain suspension geometry across extended service life.
