ARB 0770003 Air Locker Differential Case Spreader Tool

The ARB 0770003 Air Locker Differential Case Spreader is an essential specialty tool for technicians installing or servicing Salisbury-style and shim-adjusted Banjo-style axle assemblies. Achieving precise carrier bearing pre-load is critical to the longevity of any differential; this spreader allows you to safely and controllably stretch the housing casting (the "pumpkin") to insert necessary shims according to OEM specifications.

By utilizing the factory spreader sockets in the housing, this tool eliminates the guesswork and risk of damage associated with improper installation. Ensuring correct pre-load prevents common failures, including premature bearing wear, ring and pinion damage, and potential air leakage in Air Locker systems. Built for professional shop environments, it provides a highly effective solution for heavy-duty axle maintenance.

  • Precise Pre-Loading: Safely stretches axle housings for accurate shim placement without risking permanent deformation.
  • Universal Compatibility: Pre-drilled hole pattern is designed to fit most common axle types, including Dana Spicer Model 44 and other Salisbury assemblies.
  • Durable Construction: Manufactured to withstand high-force applications; includes a powder-coated parts tray for organization.
  • Mobile-Ready: Supplied in a heavy-duty carry case for easy transport and protection in the shop or field.
  • Manufacturer Part Number: 0770003
