Construction & Design

Old Man Emu Nitrocharger Plus shocks are built with robust materials and precision engineering to withstand the rigors of off-road use while maintaining smooth on-road performance.

The internal valving is carefully calibrated to match the Wrangler Unlimited JL’s suspension geometry and load characteristics, ensuring optimal shock absorption and rebound control.

Each shock is sealed to prevent contamination from dirt and moisture, extending service life and reliability. The medium-heavy load specification means the shock is reinforced to support additional weight without sacrificing responsiveness, making it an ideal choice for lifted Wranglers that carry extra gear or tow trailers.
