To keep your pride and joy performing at its best, it’s crucial to ensure your tires stay firmly planted on the road. If not, you risk a jarring ride and a loss of control. Thankfully, your suspension system is here to save the day, acting as the essential link between the wheels and the chassis. Its key players—springs, shock absorbers, and axles—work in harmony to soak up shocks and curb excessive body roll, pitch, and sway as you tackle bumps, curves, and those sharp corners.

The smooth handling and stability of your cherished ride rely heavily on the performance of its suspension system. Just like any other parts, the components that control your ride can wear down and eventually need replacing. If your vehicle isn’t gliding as it once did and you’re hearing unsettling knocking or clunking from the suspension, it might be a sign that something’s amiss. Luckily, the A-Premium online store is stocked with an array of replacement suspension kits, covering everything from control arms to brake rotors—and everything in between!

What does a suspension kit include?

A suspension kit typically includes a variety of components designed to enhance or replace the vehicle's suspension system. The specific contents can vary based on the type of kit and the vehicle model, but common elements include:

  • Springs: These may be coil springs or leaf springs that support the vehicle's weight and absorb shocks.
  • Shock absorbers or struts: These components dampen the impact of bumps and help maintain tire contact with the road.
  • Control arms: These connect the suspension system to the vehicle's frame, allowing for controlled movement of the wheels.
  • Sway bar (or anti-roll bar): This helps reduce body roll during turns, improving handling and stability.
  • Bushings: These rubber or polyurethane components provide cushioning and reduce friction between moving parts.
  • Ball joints: These allow for smooth movement between the control arms and the steering knuckles, contributing to steering control.
  • Mounting hardware: This includes bolts, nuts, and washers needed for installation.
  • Alignment components: Some kits may include parts that help adjust the vehicle's alignment for optimal handling.
