Product Details
Starting with a 400 N/mm spring rate and a 140mm length, these AST Linear Race Springs are built for serious suspension tuning. The 61mm inner diameter means they're designed to fit specific coilover bodies, offering a well-built option for racers and performance enthusiasts looking to dial in their car's handling. Linear springs offer a consistent force increase as they compress, which helps maintain predictable suspension behavior during hard cornering and braking.
These springs are a popular choice when rebuilding or upgrading coilover setups. Their consistent rate helps mechanics achieve a more predictable suspension response compared to progressive springs, especially when paired with adjustable dampers. The 140mm length is a common size, but always double-check your existing coilover spring perch dimensions to ensure a proper fit. This single spring is part of a system, so you'll need to purchase the correct quantity for your vehicle's suspension setup.
