Default Help identifying a part

Does anyone know what this spring is for? It was in the box of parts I got with my bike.

In keeping with your tradition of providing minimum information, It's a big ****ing spring.

Closest I can come is a primary adjuster spring 85-90.

The only thing I can think of is a spring that returns one of those backrests to upright position..
