Our factory specializes in precision-cast 9N4302 Cat Style J300 heavy-duty long bucket teeth, manufactured to strict OEM specifications. Engineered for high-power ground-engaging machinery, our bucket tips deliver exceptional penetration and service life in harsh environments like hard dirt, gravel, and sand.
Premium High-Spec Alloy Steel: We use strict chemical spectrographic analysis to ensure our steel contains the optimal blend of Chromium, Nickel, and Manganese, drastically reducing the risk of brittle fractures on the job site.
Advanced Heat Treatment: Every batch of 9N4302 bucket teeth undergoes precise quenching and tempering. This creates a high-hardness exterior shell for intense wear resistance while maintaining a tough internal core to absorb heavy shocks.
100% OEM Compatibility: Dimensions are rigorously controlled via custom inspection gauges. The pocket size perfectly matches the Cat J300 adapter, and the side-pin alignment guarantees quick, hammerless-friendly installation.
Full OEM/ODM Customization: We can cast your custom company logo directly onto the tooth body and provide tailor-made surface finishes (such as standard Cat Yellow, Gloss Black, or Red powder coating).

Long-Lasting: Enhanced design offers improved wear life, reducing the need for frequent replacements.
Reliable Performance: Provides excellent penetration and breakout force, making it ideal for challenging digging environments.
Increased Effciency: The Caterpillar Bucket Teeth 9N4302 are designed to make every excavaion task easy, eficient, and hassle-free
