Rear Suspension Performance Operation

Jun 6, 2019

Rear suspension plays a crucial role in determining a vehicle's handling, comfort, and overall performance. At Grafco Electric, we understand the importance of optimizing your rear suspension to achieve better control, stability, and responsiveness. In this comprehensive guide, we will delve into the intricacies of rear suspension performance operation, providing you with the knowledge and insights necessary to elevate your driving experience.

Understanding Rear Suspension Components

A successful rear suspension system relies on various components working together harmoniously. By comprehending the role and functionality of each component, you can better grasp how to improve the performance of your rear suspension. Let's explore some key rear suspension components:

1. Coil Springs

Coil springs are designed to support the weight of the vehicle and provide crucial support for the rear axle. These springs work in conjunction with other suspension components to absorb impacts, maintain tire contact with the road, and enhance handling.

2. Shock Absorbers

Shock absorbers, also known as dampers, play a critical role in controlling the movement of the suspension. These hydraulic devices absorb and dissipate the energy generated by the springs, ensuring a smoother and more controlled ride. By effectively dampening vibrations and oscillations, shock absorbers contribute to better overall rear suspension performance.

3. Sway Bars

Sway bars, also referred to as stabilizer bars or anti-roll bars, are responsible for minimizing body roll during cornering. By connecting the left and right sides of the suspension, sway bars distribute the vertical load and provide greater stability, allowing for improved steering response and reduced body roll.

4. Control Arms

Control arms, or A-arms, are crucial suspension components that connect the chassis to the wheel hub and allow for controlled movement. They work alongside the springs and shock absorbers to ensure optimal wheel alignment, rotation, and overall stability. Proper control arm alignment is vital for maintaining rear suspension performance.

Optimizing Rear Suspension Performance

Now that we have a solid understanding of the various rear suspension components, let's explore some effective strategies for optimizing rear suspension performance:

1. Upgrading Coil Springs

Consider upgrading your vehicle's stock coil springs with performance-enhancing options. High-quality aftermarket coil springs can provide improved support, reduce body roll, and enhance overall handling. Coil springs with progressive rates offer versatility by providing a comfortable ride during regular driving conditions and firmer support when encountering harsher road surfaces or aggressive maneuvers.

2. Installing Performance Shock Absorbers

Upgrade your shock absorbers to high-performance variants specifically designed to enhance rear suspension performance. Performance shocks offer increased damping capabilities, ensuring better control and responsiveness. Adjustable shock absorbers allow fine-tuning to match your driving preferences and enable further customization for different road conditions or driving styles.

3. Adding Sway Bar Upgrades

Enhance your vehicle's stability and handling by investing in aftermarket sway bars. Thicker sway bars provide greater resistance to body roll, resulting in improved cornering abilities and reduced understeer. Adjustable sway bars enable fine-tuning to match your desired level of stiffness or adapt to different driving scenarios.

4. Upgrading Control Arms

Consider upgrading your control arms to sturdier, performance-oriented options. High-quality control arms can improve suspension response, reduce flex, and enhance overall stability. Adjustable control arms offer the added benefit of fine-tuning suspension geometry to achieve optimal alignment and improved handling characteristics.


Optimizing your vehicle's rear suspension performance is essential for achieving superior handling, control, and comfort. By understanding the role of each rear suspension component and implementing effective upgrades, you can transform your driving experience.
