Old Man Emu Rear Coil Springs in Black with 260 lbf/in Spring Rate for Toyota 4Runner (2003–2024) - Pair

Old Man Emu engineers vehicle-specific coil springs to support remote travel and sustained load carrying. Additional fuel, water storage, spare components, and recovery gear place significant strain on factory suspension systems. These rear coils are calibrated to maintain ride height and improve control across uneven terrain and extended highway driving.

Micro-alloyed spring steel provides strength and fatigue resistance under sustained load. Each coil is formed on computer-controlled mandrels for dimensional consistency. Double scragging reduces internal stress and helps maintain long-term spring integrity.

Vehicle-specific tuning ensures proper seating and predictable suspension geometry. A 260-pound-per-inch spring rate supports added rear weight while preserving balanced handling. Integration with compatible Old Man Emu shock absorbers refines overall ride control.

Engineered for repeated compression cycles and demanding off-road use, these coils maintain structural stability over time. Micro-alloyed construction enhances load retention. A durable black powder-coated finish protects against corrosion and surface wear.

Precision-formed dimensions align with factory spring perches for direct fitment. Proper installation maintains suspension geometry and ride height. Professional installation is recommended for optimal performance and system integration.
