Auxiliary Axles

Fontaine Modification’s Engineering Teams are consistently developing products, improving, and looking for the next development. Our teams have the unique ability to engineer, design systems, build prototypes and execute serial production with both contract engineering and new products.

  • All designs meet FMVSS, DOT, and EPA compliance standards.
  • Electrical wiring and airline routing changes fit well into the OEM’s factory harness designs.
  • Solid Modeling is used for consistent design and manufacturing.
  • For more complicated development work, a prototype may be produced before serial production begins.

Types of Auxiliary Axles

  • Tag axles are unpowered axles added behind the drive axle(s)
  • Pusher axles are unpowered axles added in front of the drive axle(s)
