Yukon ZA G26018080 1541H 30-Spline Rear Axle for 1991-1996 Chevrolet Caprice

Vehicle Fitment

• 1991-1996 Chevrolet Caprice (GM 8.5" 10-bolt rear differential, 30-spline)

Fitment Notes

• Some retailer listings for this part also reference a "1991-1993 Chevrolet Impala" application; however, the Chevrolet Impala SS was only produced from 1994-1996, and no factory 1991-1993 Impala model exists. I was unable to independently confirm this listed application - verify directly with the seller or manufacturer if fitting an Impala
• Detailed parts cross-reference data specifies this axle for "less posi" (open differential) use; if your Caprice has a factory or aftermarket limited-slip differential, confirm the correct axle spec for that application, as posi and non-posi variants can differ in length
• 30-spline, GM 8.5" 10-bolt rear differential only - some earlier Caprice model years used a 26-spline 7.5" rear axle instead, so confirm your differential and spline count before ordering
• Sold individually - order two for a complete rear axle set

Features

• One-piece 1541H alloy axle shaft for stronger-than-stock durability
• Modern heat-treating for improved strength over factory axles

Product Description

The Yukon ZA G26018080 is a direct-fit replacement 1541H alloy axle shaft for the GM 8.5" 10-bolt rear differential found in the 1991-1996 Chevrolet Caprice. Built from 1541H alloy steel with modern heat-treating, it's designed to offer better durability than the factory axle when replacing a broken, worn, or corroded shaft, or when preparing a Caprice for towing, spirited driving, or a broader drivetrain rebuild.

This is a 30-spline axle specified for open (non-posi) differential applications, so confirming your Caprice's differential type - and that it's the 8.5" 30-spline rear rather than an earlier 7.5" 26-spline setup - is worth a quick check before ordering, since Caprice axle specs varied across model years and equipment.

This axle is sold individually - a complete rear axle set requires two. Installation involves removing the differential cover and axle retention hardware to access and replace the shaft, a job well within reach of an experienced DIY mechanic and a common step during a broader rear differential service.
