Dual axle suspension configuration: Intended for trailer designs using a dual axle suspension arrangement.
Leaf spring suspension: Includes leaf springs as part of the suspension assembly.
Rocker equalizer: Incorporates a rocker equalizer to form part of the suspension arrangement between the axle assemblies.
Mounting components included: Includes hangers, mounting brackets, and U-bolts.
OEM project support: Suspension configuration and mounting requirements can be reviewed against customer drawings and specifications.
Final suitability depends on the actual product dimensions, load requirements, installation arrangement, and compatibility with the trailer chassis and axles.

The kit includes the following components:
The leaf springs form part of the trailer suspension system. Spring dimensions, leaf configuration, material specifications, and load ratings should be confirmed for the selected model.
The rocker equalizer is part of the dual axle suspension arrangement. Its geometry and mounting positions must match the intended suspension design.
Hangers provide mounting points for suspension components. Their positions and dimensions should be checked against the trailer chassis design.
Mounting brackets support the installation of the suspension assembly. Bracket dimensions and fixing arrangements should be confirmed before production or installation.
U-bolts are included for the relevant axle and suspension mounting arrangement. Their dimensions and specifications must match the axle and installation requirements.

When selecting a suspension kit for an OEM trailer project, consider the following factors:
Trailer load requirements: Confirm the intended trailer weight and the required ratings for the complete running gear system.
Axle specifications: Check the axle dimensions and the compatibility of the suspension mounting arrangement.
Leaf spring configuration: Confirm spring dimensions, leaf arrangement, and required performance specifications.
Mounting dimensions: Review hanger positions, bracket locations, clearances, and chassis interfaces.
Component compatibility: Verify that the rocker equalizer, leaf springs, U-bolts, axles, and chassis work together as specified.
Operating conditions: Consider the intended trailer application and operating environment when confirming the final configuration.
The complete suspension system should be assessed against the trailer design rather than selecting components by appearance alone.
