Swift Tuning Accessories: Eliminate Spring Noise and Improve Coilover Performance with Swift Springs Thrust Sheets

Small Components Can Make a Big Difference in Suspension Performance

When racers think about improving suspension performance, most of the attention goes toward spring rates, shock valving, ride height, and chassis setup. However, some of the biggest gains in consistency come from addressing the small details that often go unnoticed.

One of those overlooked areas is the interface between the spring and the spring perch.

As a coilover compresses and rebounds throughout a race, the spring naturally wants to rotate. Without a smooth contact surface, friction can develop between the spring and the perch, creating unwanted resistance, inconsistent load transfer, and one of the most common complaints heard in the pits: spring noise.

That's why Swift Springs developed its proprietary Thrust Sheets.

Designed to reduce friction, improve spring rotation, and promote smoother coilover movement, Swift Thrust Sheets help racers maximize suspension efficiency while reducing unwanted noise under compression.

Reduce Spring Noise Without Compromising Performance

Anyone who has spent time around a race car has likely heard it.

That unwanted squeak or grinding noise that develops as the suspension cycles isn't just an annoyance. It can be a sign that friction is preventing the spring from moving as freely as it should.

Swift Springs' self-lubricating Thrust Sheets are engineered to create a smoother contact surface between the spring and the perch, allowing the spring to rotate more naturally as it compresses.

The result is:

>Reduced spring noise
>Smoother spring rotation
>More evenly distributed spring loads
>Improved preload consistency
>Better overall coilover performance

By reducing friction at the contact point, the spring can do what it was designed to do without unnecessary resistance interfering with suspension movement.

Why Spring Rotation Matters

A coilover spring doesn't simply move straight up and down.

As the suspension cycles through compression and rebound, the spring naturally twists and rotates. If that movement is restricted, the load can become unevenly distributed throughout the spring.

Over time, this additional friction can affect preload consistency and reduce the suspension's ability to respond predictably.

Swift Thrust Sheets help eliminate that issue by allowing the spring to rotate smoothly around the perch under compression.

For racers looking for every possible advantage, reducing unnecessary friction can improve repeatability and create a more predictable suspension package from one lap to the next.

Designed to Work with Most Coilover Systems

One of the biggest advantages of Swift Thrust Sheets is their versatility.

These proprietary self-lubricating sheets are designed to work with most coilover systems and are available in three popular sizes:

Whether you're running a 60mm, 65mm, or 70mm setup, Swift has a solution designed to improve spring movement and reduce unwanted noise.

What's Included in Each Kit?

Each kit is designed to service two springs and includes:

• 4 self-lubricating Thrust Sheets

• 4 stainless steel washer sheets

The combination of these components creates a durable, low-friction surface that helps improve spring movement throughout the suspension's operating range.

Small Details Create Race-Winning Results

At Swift Springs, suspension development isn't limited to springs alone.

The goal has always been to provide racers with complete suspension solutions that improve consistency, repeatability, and on-track performance.

Sometimes, the difference between a good setup and a great setup isn't a major spring change. It's addressing the smaller components that affect how efficiently the entire suspension package works together.

By reducing friction, improving spring rotation, and eliminating unwanted noise, Swift Thrust Sheets help racers get the most out of their coilover systems.
