SACHS Nivomat self leveling technology was developed as a means to improve the safety and performance of vehicles loaded with extra weight in the rear of the vehicle (luggage, towing, etc.) without the use of external pumps or springs. Nivomat shocks will level a heavily loaded vehicle within one-hundred yards of movement. TRW Shocks and Struts are intelligently engineered to restore original handling dynamics while designed to meet the highest safety, comfort, performance, and quality standards. SACHS products have the best dampening characteristics with an application-tuned valve pairing longevity with superior comfort and control for vehicles in any road condition.SACHS Nivomat self leveling technology was developed as a means to improve the safety and performance of vehicles loaded with extra weight in the rear of the vehicle (luggage, towing, etc.) without the use of external pumps or springs.
