• Requires matching hinge geometry for proper door clearance and alignment

General Specifications

Installation Notes

The R48-1052 should be installed after supporting the cab door, examining the existing hinge attachment points, and checking the surrounding mounting surfaces for deformation, corrosion, or damaged fastener threads. Once the hinge is secured, adjust the door position as required, inspect the clearance around the cab opening, and verify that the door swings freely and engages its latch without binding.

Always verify the original hinge part number, Kenworth or Peterbilt model, door mounting position, hinge geometry, and cab attachment arrangement before installation.
