About this part

Product Details

If you're rebuilding your coilovers or looking to fine-tune your suspension's stiffness, these AST Linear Race Springs are a solid option. They offer a consistent spring rate across their travel, meaning the force applied by the spring increases linearly with compression. This predictable behavior is crucial for performance driving where precise suspension feedback is key.

These springs measure 150mm in length and have a spring rate of 100 N/mm, which translates to about 571 lb/in. The 61mm inner diameter is a common size for many coilover applications, making them a versatile choice for custom setups or replacements. The linear design ensures that as you compress the spring, the resistance builds steadily, providing a well-controlled ride that doesn't become overly harsh or too soft unexpectedly.
