Old Man Emu Nitrocharger Plus Front Coilover Shock for 5th-Gen 4Runner (2010–2024)

Old Man Emu Nitrocharger Plus Front Shock is designed to provide stable suspension performance across a wide range of driving conditions. With vehicle-specific damping and adjustable spring seat positions, it allows the suspension system to be tuned for varying loads, accessories, and driving environments.

The twin-tube shock body is built from heavy-gauge steel to improve durability and protect internal components during off-road use. A triple-lip oil seal helps prevent contamination, while a large Teflon-infused bronze bushing reduces friction and improves long-term reliability.

The shock features a five-position adjustable spring seat system with included coil seat spacers, allowing ride height and preload adjustments to match different vehicle setups. Vehicle-specific polyurethane and rubber bushings improve longevity and reduce vibration.

An integrated high-flow piston helps maintain consistent damping by reducing oil aeration and managing internal temperatures. Multi-deflective disc valving improves rebound and compression control, delivering stable handling and improved steering response.

High-quality internal components, nitrogen gas charging, and low-friction materials help maintain consistent shock performance over time. The free-flowing internal design and reinforced sealing system contribute to long service life under demanding conditions.
