Rear Coil Springs in Black with 318 lbf/in Spring Rate and 390 mm Free Height for 4th-Gen 4Runner (2003–2009) - Pair

These coil springs are designed for the 4th-Gen 4Runner, providing a matched pair of rear suspension springs manufactured for the vehicle's intended application. For owners who rely on their vehicles for commuting and off-roading, spring quality is an important consideration when maintaining or refreshing the suspension.

Old Man Emu uses microalloyed spring steel to provide strength and durability. The material is selected for demanding automotive applications where springs must continually respond to changes in road surface and vehicle weight.

Each spring is double-scragged to reduce internal stress and extend service life. This manufacturing step improves durability as the suspension cycles through compression and extension during everyday driving and off-road use.

Computer-precision mandrels form the coils and maintain consistent dimensions during production. The springs are designed to exact specifications, supporting reliable fitment when matched to the correct 4th-Gen 4Runner configuration.

These rear coil springs' construction, precision manufacturing, and vehicle-specific specifications make them a practical choice for owners prioritizing dependable suspension components for everyday and four-wheel-drive use.
