Shim Kit Dana 60 & 61

The Shim Kit Dana 60 & 61 by ALLSTAR PERFORMANCE is a comprehensive differential assembly solution engineered for technicians and builders working with Dana 60 and Dana 61 differentials in high-performance and heavy-duty applications. This kit addresses the critical task of pinion depth and carrier bearing preload adjustment, two fundamental specifications that directly impact differential longevity, noise characteristics, and driveline efficiency. Whether you're rebuilding a rear axle after hard use or installing an upgraded differential in a truck or performance vehicle, proper shimming is non-negotiable for reliable operation.

This kit includes pinion retainer shims, pre-load shims, a crush sleeve, pinion nut, and bolts—all precision components required to establish correct mesh geometry between the ring and pinion gears. The shim stack method allows fine-tuning of pinion position to achieve the factory-specified backlash and contact pattern, while the pre-load shims control bearing preload on the differential carrier. Proper preload eliminates side-to-side movement that causes deflection, gear noise, and accelerated bearing wear. ALLSTAR PERFORMANCE manufactures these shims and fasteners to OEM tolerances, ensuring repeatability and compatibility with Dana 60/61 housings across truck, SUV, and racing platforms.

This kit is essential for differential technicians, engine builders, and off-road enthusiasts tackling axle rebuilds where factory specifications must be restored or upgraded carriers are being installed. Professional shops and DIY builders benefit from having all shimming hardware in one package, reducing downtime and ordering delays. The compact 11.2 x 1.9 x 11.8 inch kit fits easily in a toolbox and weighs just 2.5 lbs, making it convenient for job-site transport. Compatibility is confirmed for Dana 60 and Dana 61 differentials; verify your specific carrier type and ring gear diameter before ordering to ensure shim thickness accuracy.
