Most budget shocks use oil alone, but HPR’s nitrogen-charged design is a game-changer. Here’s the science: nitrogen (at 0.8MPa) pressurizes the oil, preventing cavitation—small bubbles that form when oil heats up, causing damping loss. Our shocks use German Fuchs Titan Race oil, which stays viscous from -53°C to 180°C, ensuring consistent performance in arctic cold or desert heat. The NOK seals (Japan’s leading brand) add another layer of protection, blocking dust and moisture that degrade OEM seals in 12-18 months.
Compare that to standard shocks, which lose 20% damping efficiency after just 10 hours of off-roading. HPR shocks, tested on the Baja 1000 course, retain 95% efficiency over 50+ hours. For vehicles like the Toyota Prado 150, where reliability is non-negotiable, our nitrogen-charged shocks are the only choice. Read our deep-dive into shock technology and see why every component—from the seamless steel tube to the chromed piston rod—matters for longevity.
