R&P Knowledge Hub
An equalizer links adjacent slipper springs in multi-axle trailer suspension systems. It allows one axle to rise while the other lowers, helping maintain consistent tire contact and balanced load distribution. Over time, pivot holes and bolts can wear, leading to uneven tire wear or suspension noise. When rebuilding suspension components, verify spring width, eye diameter, bolt sizes, and hanger spacing before ordering replacement hardware.
