    344 BUSHING – RUBBER

    The 344 Bushing is made of rubber and can be ordered for replacement in our 320 and 330 Hinge Assemblies. Rubber is our standard bushing material and is suitable for most applications.
  • Accessories

    344A BUSHING – POLYURETHANE

    The 344A Bushing is made of polyurethane and can be ordered for replacement in our 320 and 330 Hinge Assemblies. Polyurethane bushings typically yield 2 to 3 times the service life of rubber. They are ideal and highly recommended for use in off-road and/or severe applications.
