Suspension technology has come a long way in recent years, with advanced materials and engineering principles playing a crucial role in how a vehicle handles and feels on the road. One of the more advanced features found in SLRspeed coilovers is the use of nitrogen-filled shocks—a component that’s often overlooked but makes a significant difference in performance, durability, and consistency. Understanding the role of nitrogen in these shocks can help you appreciate why SLRspeed has chosen this technology as a cornerstone of their suspension systems.

At the most basic level, a shock absorber’s job is to control unwanted motion in the suspension—damping the effects of road irregularities, cornering forces, acceleration, and braking. Traditional shock absorbers use oil to perform this task, but oil alone can be susceptible to cavitation when the suspension is under heavy load. Cavitation occurs when the fluid inside the shock becomes aerated, leading to inconsistent performance, spongy handling, and heat build-up. This is particularly problematic in high-stress environments like drifting or spirited driving.

This is where nitrogen comes in. SLRspeed coilovers use pressurized nitrogen gas in conjunction with hydraulic oil to eliminate cavitation. The nitrogen creates a pressurized chamber inside the shock that helps maintain the separation of gas and oil, ensuring consistent damping force even under aggressive or prolonged use. The result is a shock absorber that responds quickly and predictably, with reduced fade and better overall control.

For performance drivers, especially those involved in drifting, this translates into more confidence behind the wheel. The suspension remains consistent lap after lap, allowing the driver to trust the car’s behavior during quick transitions and sustained sideways motion. Whether you’re initiating a drift or powering out of a corner, the nitrogen-filled shocks in SLRspeed coilovers deliver the stability and responsiveness needed to maintain control.

But the benefits aren’t limited to the track. Even daily drivers will notice the difference in ride quality. The nitrogen charge helps smooth out small road imperfections while keeping the vehicle planted during braking or cornering. It’s a subtle but significant improvement that enhances both comfort and safety.

Durability is another advantage. Because nitrogen-charged shocks operate more efficiently and maintain internal pressure, they’re less prone to wear and overheating. This means fewer performance dips over time and longer service life compared to traditional oil-only shocks.

SLRspeed’s inclusion of nitrogen-filled shocks isn’t just a technical upgrade—it’s a commitment to quality and performance across every driving scenario. Whether you’re drifting, daily driving, or doing a mix of both, these shocks ensure your suspension delivers consistent excellence.
