Engineered for drivers demanding unparalleled performance and control, the TrakRyder Foam Cell series is the ultimate solution for harsh terrain, heavy load carrying, and towing. These units are ideal for 4x4s, workhorses, and vehicles equipped with heavy accessories (bullbars, winches, canopies). They offer all the advantages of Nitrogen Gas shocks but are enhanced with Heavy-Duty Twin-Tube Technology for exceptional durability under permanent weight.
At the heart of the design is the advanced Foam Cell Technology combined with a massive 40mm bore and piston. Unlike standard shocks where gas and oil can mix, the closed-cell foam sleeve ensures full oil contact with the housing. This design virtually eliminates shock fade by preventing cavitation and aeration (the foaming of oil caused by rapid movement). By stopping bubbles from forming, the shock ensures consistent damping pressure, which is critical for maintaining stability when hauling heavy loads or navigating corrugated tracks.

Common Questions: Foam Cell vs. Nitrogen Gas
What is the main difference between Nitrogen Gas and Foam Cell shocks?
While Nitrogen Gas shocks are an excellent upgrade for general driving and light loads, Foam Cell shocks are engineered for heavy-duty applications. The primary difference lies in the Foam Cell ability to maintain performance without fading, making the product superior for vehicles that are constantly loaded or driven in extreme conditions.
When is the Foam Cell option recommended over Nitrogen Gas?
The Foam Cell model is the preferred choice if the vehicle is heavily accessorized (bullbars, winches, roof racks), used for trade purposes, or regularly tows heavy trailers. The larger oil capacity and cooling efficiency provide the necessary stability and control that standard shocks cannot maintain under such weight.
Does the 40mm bore make a difference?
Yes. The 40mm bore and piston provide a dramatically increased oil capacity compared to original equipment. More oil means better heat dissipation (cooling), which ensures the shock absorber continues to work effectively even during long trips with heavy loads or on rough roads.
