The RT3064 trailer leaf spring hanger is a suspension component designed to secure a leaf spring to a compatible trailer frame. Measuring approximately 1-15/16 × 3-15/16 × 3-1/4 inches, it is used in tandem-axle suspension assemblies. This hanger is intended for compatible trailer suspension configurations and should be matched to the original component's dimensions and mounting arrangement before installation. Suspension hardware and related components may be sold separately.
