This equalizer kit is designed for use on 10,000–15,000 lb trailer suspension systems equipped with 3" wide slipper springs. The equalizer connects adjacent springs within a tandem or triple axle configuration, allowing the suspension to distribute load between axles as the trailer travels over uneven surfaces. The equalizer is not side specific and may be installed on either the left or right side depending on suspension layout.
