The length of your cargo determines the number of tie downs: • 5 feet or less 1,100 pounds or less = 1 tie down • Over 1,100 pounds but 5 feet or less = 2 tie downs • 5-10 feet = 2 tie downs • Longer than 10 feet = 2 + 1 for every additional 10 feet or fraction thereof.
Torque is the tendency of a force to move around a point. In other words, torque refers to twisting force. The unit of measure for torque that we all know, the "ft-lb," "lb-ft," or "foot-pound" is the amount of turning force applied to move one pound a distance of one foot around an axis at a radius of one foot.

How to measure spring rate: enter your inputs into our spring force calculator and review your answers. Outputs include spring ratings and spring constant. Spring ratings are a constant, example: If your spring rate is 10 lbsf/in then it will take you 10 lbsf to force to compress the spring one inch of distance.
