The Spring Spiral Torsion 1.25" is used on the front and rear arms of the Thunderstone 7000 electric tarp system. This torsion spring helps provide the arm tension needed for smooth tarp operation, assisting the system as the tarp opens and closes across the trailer.

Built for use in electric tarp arm assemblies, this replacement spring is ideal when the original spring is worn, damaged, weak, or no longer maintaining proper arm tension. Replacing a fatigued torsion spring can help restore consistent tarp movement and reduce strain on the tarp system.
