Replacement Pinion Depth Shim for Dana 80 Differential - Precise Fit

In this review the Yukon Gear & Axle replacement pinion depth shim for Dana 80 is evaluated for shop technicians and serious DIY installers who need a precise shim solution for heavy-duty rear ends. The bottom line is that this shim pack delivers a tailored, machined set of spacers that simplify achieving correct pinion depth, especially when fitting 10.5 sterling pinions or avoiding crush sleeves. It is a straightforward, vehicle-specific replacement that emphasizes quality construction and predictable installation results for differential setup.

Key Features

• Precision machined: Each shim is cut to tight tolerances so installers can dial in pinion depth without guessing.
• Vehicle specific fit: The kit is tailored to Dana 80 applications, reducing the risk of mismatched thicknesses during setup.
• Compatible with 4.125 in od: The shim set matches the 4.125 in outer diameter requirement called out for the application.
• Easy to handle weight: At around 0.81 pounds packaged, it is compact and simple to transport to the bench or vehicle.
• Alternative to crush sleeves: Users report the shims give more repeatable preload adjustments than relying on crush sleeves alone.

Who It's For

This shim pack is aimed at professional mechanics, drivetrain specialists and experienced DIYers working on Dana 80 differentials who want a set of accurately machined pinion depth shims. It is particularly useful when performing a 10.5 sterling pinion installation or when a vehicle-specific shim set saves time during carrier and bearing setup.

Those who should look elsewhere include casual owners who rarely service differentials and would rather have a complete rebuild kit including bearings and races; this product is a focused shim solution and not a full bearing or gear set.

Pros & Cons

Pros

• High quality, precision machined parts that simplify achieving correct pinion depth.
• Vehicle specific design reduces the need for additional modification or trial shims.
• Preferred by many users over crush sleeves for repeatable carrier setup.

Cons

• Some customers note mixed opinions on thickness consistency and the range of sizes included, so final selection may still require careful measurement.
