Description

Part #: KDT903

Whiteline's differential insert bushings work within the voids of the original factory bushing to ensure pinion angles are maintained while delivering an improved gear shift resulting in reduced initial torque loss and greater power transfer to the wheels.

Features:

  • Featuring premium anodized alloy materials, Whiteline alloy products are anodized providing a long-lasting protective barrier to corrosion and wear but they look great too.
  • Inserts are designed to work with the original factory bushing rather than replacing it.
  • Install guide included providing detailed instructions on how to install your new Whiteline purchase.
  • Internal grease reservoirs provide continual self lubrication for optimum friction management.
  • Protective plating on all metal components acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
  • Protective powder coating acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
  • Specially bonded design for optimised strength typically required in high load bearing applications.
  • Supplied with extreme pressure molybdenum disulphide (LM) based grease for extended life.
  • Whiteline's latest technology synthetic elastomer formulation boasts resistance to oil, grease, ozone and weathering.
