Struts are a key part of modern vehicle suspension systems, combining the functions of a shock absorber with the structural support of a coil spring. Unlike standalone shock absorbers, struts also bear part of the vehicle’s weight and play an important role in maintaining suspension geometry. Positioned in both front and rear suspension systems, struts are particularly common in the MacPherson strut design, where they integrate directly with the steering mechanism. A strut consists of a steel tube housing that contains a shock absorber along with a coil spring mounted around it. This combination allows struts to absorb road shocks while also supporting the vehicle’s body. Struts are crucial for alignment, steering response, and overall stability. They are heavier and more durable than standard shock absorbers, typically lasting up to 120,000 kilometers with proper maintenance. When struts wear out, drivers may experience clunking noises, poor handling, and uneven tire wear. While replacement costs are higher compared to shocks, struts provide both damping and load-bearing functions, making them a vital suspension component. They are widely used in cars, SUVs, and light trucks to ensure safety, ride comfort, and stability.
