Diff Shims Dana 60

The Diff Shims Dana 60 from RATECH is a precision steel shim designed to maintain proper bearing preload and gear backlash in Dana 60, 70, 70-HD, and 70-U differentials. These shims are essential wear items for anyone rebuilding or servicing heavy-duty differentials, whether for off-road vehicles, trucks, or performance applications. Proper shim selection ensures correct ring gear geometry, noise reduction, and extends differential component lifespan.

Manufactured from hardened steel in natural finish, the Diff Shims Dana 60 provide consistent thickness and load distribution across pinion bearings. These shims work in conjunction with bearing preload measurements taken during differential assembly to establish the correct clearance between ring and pinion gears. RATECH's precision engineering ensures tight tolerances that prevent excessive play, which would otherwise cause gear noise, premature wear, and potential catastrophic failure under high load or torque conditions. The compact dimensions (2.05 x 0.3 x 3.05 inches) allow easy installation during differential teardown and reassembly.

Differential technicians, rebuilders, and DIY enthusiasts working on Dana 60 axles for trucks, SUVs, or performance vehicles rely on quality shims to achieve factory-correct preload specifications. These shims are sold individually, allowing rebuilders to adjust total stack height precisely based on bearing preload measurements and gear mesh requirements. Installation requires complete differential disassembly and should be paired with bearing preload gauges and a rebuild kit for optimal results. Compatibility spans Dana 60, 70, 70-HD, and 70-U applications.
