R&P Knowledge Hub
Slipper springs are commonly used in tandem axle trailer suspension systems where the rear of the spring slides inside a hanger instead of using a second eye. The front eye mounts rigidly while the rear slipper allows controlled movement during axle articulation. Proper spring length, eye diameter, camber height, and center bolt location must match the existing suspension geometry. Always verify measurements against the original spring before installation to maintain ride height and axle alignment.
