These springs sit around the damper unit at each rear shock and carry the load the shock damps out. The 110 lb rating tells you the spring's stiffness, which is how the factory and suppliers differentiate these springs from lighter or heavier options for the same shock body.
The catalog record doesn't tie this to one specific model, so before you order, check what shock units you're running and confirm this spring rate matches what you need. Call the shop if you're not sure and we'll help sort it out.
