12in x 2.5in x 150# Coil Spring

The 12in x 2.5in x 150# Coil Spring from Chassis Engineering is an essential suspension component designed for street, strip, and road-course vehicles that require responsive handling and reliable load support. This coil spring is ideal for automotive enthusiasts and professional mechanics who prioritize chassis geometry and performance tuning, whether for daily driving or competitive racing.

Engineered with a 150-pound rate, this coil spring is perfect for mid-weight applications, offering predictable spring behavior while minimizing ride harshness. The design ensures linear spring rates that effectively translate driver input into suspension response, preventing issues like binding or coil bind. Its compact dimensions allow for easy integration into various suspension setups without compromising usable travel.

This coil spring is suitable for a range of applications, including street cars, bracket racers, and road-course competitors, accommodating both independent and solid-axle suspensions. The combination of stiffness and compliance helps reduce body roll and dive during braking while maintaining comfort over uneven surfaces, making it an excellent choice for setups utilizing adjustable coilovers or double-adjustable shocks.
