4T5501

The 4T5501 is a Caterpillar-compatible ripper bucket tooth from the R500 series — a heavy-duty ripper tooth for large bulldozers performing deep ripping in rock, frozen ground, and heavily compacted material. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for heavy bulldozers for mining overburden removal and large-scale earthmoving.

Ripper Profile — Application & Performance

Built for extreme ripping operations, the ripper profile features a reinforced cross-section and hardened tip designed to break through frozen ground, compacted fill, asphalt, and rock formations. The geometry distributes impact forces across a wider area to prevent premature tip failure under heavy shock loads, while the elongated shape provides effective prying leverage.

Material & Durability

At 25.1 kg, this tooth is built for large bulldozer class equipment. This heavy-duty tooth is forged from heat-treated alloy steel and finished to HRC 48-58, with the higher hardness range available for demanding rock and mining applications. The increased cross-section provides greater resistance to the bending loads that occur during heavy ripping and prying operations. The heat treatment process is tightly controlled to prevent internal stresses that could cause premature failure under shock loading.
