AST Helper Springs - 70mm Length x 50 N/mm Rate x 75mm ID - Set of 2

If you're working on a coilover setup and need to keep your main springs seated properly, these helper springs from AST are a solid option. They're designed to provide a small amount of preload to the main spring, ensuring it stays in place even when the suspension is fully extended. This is especially important for maintaining consistent suspension geometry and preventing unwanted noise or rattling.

These particular springs measure 70mm in length and have a spring rate of 50 N/mm, with a 75mm inner diameter. This size is common for many aftermarket coilover systems. They are well-built and will do the job of keeping your main springs loaded. Just remember to check your specific coilover manufacturer's recommendations for spring dimensions and rates to ensure compatibility.
