Description

The K-Tuned 100-250-450 B coilover spring is engineered to deliver consistent performance and enhanced traction by minimizing spring bowing. This barrel-type spring has a 2.5-inch inner diameter, a 10-inch length, and a 450 lbs/inch spring rate, with usable stroke of 5.3 inches and a maximum stroke of 7 inches. Developed using extensive testing data from various racing disciplines, these springs are built to meet the demanding standards of American motorsports, including oval track, drag racing, and off-road applications. The reduced unsprung mass contributes to improved vehicle dynamics, leading to better responsiveness during cornering and acceleration. The barrel design facilitates easier installation and adjustment, allowing for precise tuning of ride height and handling characteristics. The maximum outer diameter of 4 inches (except for B5 and B3 series) aids in maintaining compatibility with tight suspension setups, preventing interference with other suspension components.
