Fitment Notes

Fits late-style GM 14-Bolt 10.5" full-floating rear axles with M8 metric cover bolts (1989 and newer design only)
Does NOT fit 1973-1988 early-style GM 14-Bolt axles - those use 3/8" cover bolts (see YHCC-GM14T-S)
Does NOT fit the GM 11.5" AAM 14-Bolt axle found in 2001+ Silverado/Sierra 2500HD and 3500HD trucks (some models transitioned to 11.5" after 2001 - verify axle ring gear size before ordering)
Does NOT fit the GM 14-Bolt 9.5" semi-float (C-clip) axle
Does NOT fit dual rear wheel (DRW/dually) trucks - most were equipped with Dana 70 rear axles
Verify axle ring gear diameter (10.5") and metric bolt pattern before ordering

Product Description

The Yukon Gear & Axle YHCC-GM14T-M Hardcore Differential Cover is engineered for the late-style GM 10.5" 14-bolt full-floating rear axle with metric M8 cover bolts, covering a wide range of 3/4-ton and 1-ton Chevrolet and GMC trucks, vans, and SUVs from 1989 through 2015. Built from thick-walled nodular iron, it delivers a serious upgrade over the factory stamped steel cover, protecting your differential's gears, locker, and internals from rocks, trail impacts, and debris that can crack or destroy a stock cover.

Beyond impact protection, the YHCC-GM14T-M strengthens housing rigidity to minimize flex under heavy towing and off-road torque loads - helping maintain proper gear mesh and prolonging the life of internal components. Its contoured inner surfaces speed up oil circulation for better heat dissipation, while the included magnetic drain plug continuously captures metallic wear particles to keep gear oil cleaner between service intervals.

Installation is straightforward using the factory 14-bolt mounting pattern with the included M8 high-strength steel fasteners and pre-cut gasket. The black powder coat finish and stainless-steel accent plate give it a clean, purposeful look. This cover is designed strictly for the late 1989-and-newer GM14T axle with metric M8 bolts - owners of 1973-1988 early-style GM 14-bolt axles should reference the 3/8" bolt version (YHCC-GM14T-S) instead.
