Sachs 316 658 Gas Pressure Monotube Front Shock Absorber

The Sachs 316 658 is a gas pressure monotube shock absorber designed for front suspension applications. Engineered to OE standards by ZF Sachs AG — part of the ZF Friedrichshafen group and one of the most respected suspension manufacturers in the world — this shock absorber delivers precise damping performance and long-term durability.

The monotube design pressurizes the working cylinder with hydraulic oil and high-pressure gas separated by a floating piston. This configuration prevents oil foaming and aeration under demanding driving conditions, keeping damping force consistent whether on smooth highways or rough surfaces. The single-tube architecture also allows installation in any orientation and promotes better heat dissipation compared to conventional twin-tube designs.

Key Features:

• Monotube gas pressure design — operates at high internal pressure (approx. 25–30 bar) for consistently responsive damping
• Floating separating piston — provides leak-proof separation of oil and gas, eliminating foaming or bubble formation in the hydraulic oil
• OE-quality construction — meets or exceeds original equipment specifications for fit, function, and longevity
• Bottom fork / top pin mounting — direct OE-style fitment for straightforward installation
• All-position capable — monotube architecture allows installation in any position without performance compromise
• Manufactured by ZF Sachs AG — a brand trusted by leading automotive manufacturers as a factory-fitted component

The Sachs 316 658 is sold individually (1 per pack). It is a direct-fit replacement shock absorber that restores like-new handling, road grip, and ride quality to vehicles with worn or damaged front suspension components.
