Old Man Emu Front Coil Springs in Black with 588 lbf/in Spring Rate for 5th-Gen 4Runner (2010–2024) - Pair

Old Man Emu coil springs are designed to support vehicles carrying expedition equipment, daily cargo loads, or off-road recovery gear. Rather than focusing only on lift height, engineering priorities center on improving ride composure and suspension control when vehicle weight changes. Matching these springs with Old Man Emu shock absorbers creates a more refined and cohesive suspension system.

Each coil spring is manufactured from micro-alloyed spring steel for improved resistance to corrosion and metal fatigue. The springs are double scragged during production to reduce internal stress and improve service life under repeated compression cycles.

Computer-precision mandrel forming ensures consistent coil spacing and dimensional accuracy for proper vehicle fitment. Variable-rate coil architecture allows progressive spring response as load demand increases during driving or cargo transport.

A 588 lbf/in spring rate enhances front suspension stability during braking, cornering, and uneven terrain travel. The design reduces excessive front-end dive while maintaining smoother handling characteristics for daily driving and long-distance travel.

Matte black powder coat finish protects against rust, moisture, and trail debris damage. High-strength material composition and controlled manufacturing processes help maintain ride height consistency and structural integrity across extended service life.
