This 6" spiral torsion spring, also called a clock spring, is made of steel. This torsion spring provides the tension needed for the tarp arms to move back and forth on your system. Place them on the lower arms, on the arm plug, of your system and the springs will be held in place at the pivot point. Our 4-Spring system can be used on dumps that are 10’ to 24’ long.
This spring is used in most 4-spring and 5-spring aluminum electric and manual aluminum tarp systems, as well as most 4-spring and 5-spring steel electric and manual tarp systems.
