Sachs 444 239 Nivomat Self-Leveling Rear Shock Absorber - 444 239

The Sachs 444 239 is a Nivomat self-leveling monotube shock absorber designed to automatically maintain optimal ride height on vehicles carrying extra rear weight from cargo, passengers, or towing. Sachs invented Nivomat technology to improve safety and performance of vehicles loaded with extra weight, restoring the vehicle to its original ride height within one hundred yards without requiring external pumps, compressors, or electronic controls.

How Nivomat Technology Works:

A self-contained pumping system inside the Nivomat provides the energy necessary for adjusting the optimum height level, which is generated by the relative movements between the axle and vehicle body. Since Nivomat is mechanical, the vehicle needs to be moving before the pump starts to work and it takes about a mile to a mile-and-a-half of travel before the vehicle reaches its optimal level point. As the vehicle experiences normal suspension movement over regular road surfaces, the internal pump mechanism automatically increases accumulator pressure to lift and level the vehicle.

Key Features:

• Low friction seal with synthetic NBR rubber that is highly wear resistant and can withstand temperatures to 260 degrees F
• Sintered metal valves that enable precise oil flow with tight tolerances for precise tuning of compression and rebound rates
• Polished working cylinder drawn to precise dimensions and polished ultra-smooth to prevent piston band wear while reducing friction and heat
• Monotube design with hydraulic piston, tube and accumulator
• Requires no external plumbing, compressor or height sensing device to level the vehicle

Benefits:

• Maintains proper ride height regardless of load conditions
• Prevents rear sag when towing or carrying heavy cargo
• Maintains proper headlight beam alignment
• Improves vehicle stability and handling under load
• Enhances safety and comfort for all occupants
• No maintenance required - fully automatic operation

This is a rear shock absorber sold individually. It's recommended to replace shock or strut in pairs (passenger and driver side at the same time). Designed for vehicles equipped with factory load-leveling suspension systems.
