The life of a suspension coil is directly related to the design and materials used. These springs are designed to be as light as possible with maximum deflection and simultaneously endure the stresses of the extreme conditions common to drag racing. These springs are designed and manufactured to retain their rate and free length for several seasons. Under normal racing applications, a properly designed and manufactured spring will not lose free length. FITMENT 5″ Spring / Double Adjustable Shocks 6″ Spring / Triple Adjustable Shocks FEATURES Ultra-Lightweight for Reduced Unsprung Mass. Each Spring is Individually Tested. Highest Linearity and Guaranteed Consistency.

Force (Pound-force): The pound-force (lbf) is a unit of force in the English system of units. It is the force exerted by gravity on a one-pound mass. In the context of torque, it is the force applied in a rotational manner. Moment Arm (Inch): The moment arm is the perpendicular distance from the axis of rotation to the point where the force is applied. In the case of a pound-force inch, the moment arm is one inch. When you combine these two components, you get a measure of torque. Mathematically, torque (τ) is calculated as the product of force (F) and the moment arm (r): τ=F⋅r In the case of a pound-force inch, if a force of one pound-force is applied perpendicularly to a moment arm of one inch, the resulting torque would be one pound-force inch. This unit is commonly used in various engineering applications, such as in the specifications for motors, screws, and other rotating machinery. Engineers and technicians use torque values to ensure the proper functioning and safety of mechanical systems by specifying the amount of rotational force required for certain tasks. Understanding torque is essential in designing and maintaining machinery, as it influences the motion and stability of rotating objects. The pound-force inch provides a convenient unit for expressing torque in a way that aligns with the common units of force and length in the English system.
