Coilover Spring 10in x 2.5in x 150lb

The SWIFT SPRINGS Coilover Spring 10in x 2.5in x 150lb (Part Number 100-250-150 B) is a precision suspension component engineered for high-performance applications requiring controlled spring rate and consistent load management. This coil-over barrel spring delivers 150 pounds per inch of spring rate across a 10-inch compressed length, making it suitable for off-road recovery rigs, performance suspension builds, and tactical vehicle platforms where predictable spring behavior under dynamic load is critical.

The 2.5-inch inner diameter accommodates standard coilover shock bodies and mounts, while the 150 lb/in rate provides firm damping control without excessive harshness on rough terrain or tactical deployment routes. Black powder coat finish protects against corrosion in harsh field environments—critical for vehicles operating in coastal, desert, or wet climates where salt air and moisture degrade uncoated steel springs. At 2.99 pounds per spring, this component integrates into suspension systems without significant unsprung weight penalty. The barrel design concentrates load distribution evenly across coils, extending service life and preventing premature fatigue failure under sustained off-road or operational stress.

Operators and technicians working on expedition rigs, light-duty recovery vehicles, or custom tactical platforms rely on SWIFT SPRINGS components where OEM springs prove insufficient. The 150 lb/in rate bridges the gap between comfort and control, handling payload weight while maintaining adequate articulation on uneven ground. This spring pairs effectively with complementary dampers rated for 150 lb/in applications, ensuring matched suspension geometry. Professional installation with properly calibrated shocks ensures optimal performance and longevity.

Coilover springs are essential upgrades for vehicles transitioning from standard duty to high-load or high-mobility roles. The SWIFT SPRINGS 150 lb/in specification sits in the mid-range of performance springs, offering tuneability without extreme stiffness that would compromise ride quality or require specialized installation expertise. This balance makes it the choice for field teams and operators prioritizing reliability and adjustability in demanding environments.
