The 78264 Chevy refers to a specific GM parts numbering system that identifies components designed for Chevrolet vehicles produced over several decades. Understanding this code is essential for anyone looking to source original equipment manufacturer (OEM) parts or high-quality aftermarket replacements. This number typically corresponds to a bracket, mount, or structural element, and verifying its exact specifications ensures a precise fit for your model year.
When searching for parts associated with the 78264 designation, compatibility is the primary concern for DIY enthusiasts and professional mechanics alike. Chevrolet’s parts database links this code to specific vehicle platforms, making it crucial to cross-reference your VIN or consult a parts specialist. Installing the correct component prevents rattling, stress on adjacent systems, and potential safety hazards down the road.
Identifying the Correct 78264 Component
Before ordering, you must determine whether 78264 refers to a bolt, bracket, sensor housing, or another hardware item. Visual inspection of your current part is the most reliable method, as dimensions and thread pitch vary significantly within the GM ecosystem. Comparing the old part to catalog images eliminates the risk of ordering a component that does not align with the mounting points.
Year and Model Specifics
Year-specific variations dictate whether the 78264 part is interchangeable between a 1995 Suburban and a 2003 Tahoe. Emissions regulations and engineering updates during this period often resulted in subtle changes to bracket geometry and mounting configurations. Confirming the exact application protects against fitment issues that could compromise the integrity of the repair.
Model Year | Vehicle Platform | Component Type
1999-2006 | GMT800 (Tahoe, Suburban) | Suspension Bracket
2007-2014 | GMT900 (Yukon, Yukon XL) | Crossmember Support
Material Quality and Construction
Aftermarket suppliers often replicate the 78264 part using different grades of steel or composite polymers. OEM components are typically stamped from high-carbon steel, offering superior resistance to fatigue and corrosion. If you choose an alternative, look for zinc or manganese plating to protect against rust, especially in regions that use road salt heavily.
Installation Best Practices
Proper torque specifications are non-negotiable when securing a critical mount or bracket. Over-tightening can strip the threads or deform the mounting surface, while under-tightening leads to vibration-induced failure. Using a new hardware kit during the installation ensures that the fasteners are not brittle or corroded, which extends the life of the repair.
Finally, a test drive on various road surfaces validates the success of the repair. Listen for any residual noise and check for interference with nearby components. Addressing the 78264 part with diligence ensures the vehicle maintains its intended performance and reliability for years to come.
