4T4503 Ripper Tooth Point 4T-4503 Bucket Ripper Tooth for D9

4T4503 D9 Chisel Tip — Product Description

The 4T4503 ripper tooth is a direct-fit wear part built for D9  dozers working in abrasive rock. Each tip is cast from high-strength alloy steel, quenched and tempered to a uniform 47-54 HRC core, so penetration stays consistent from the first pass to the last.

Key Features

• Hardness tested at three points per batch, report supplied with goods
• Tight bore tolerance on the pin hole for a rattle-free fit
• Balanced weight distribution reduces side load on the shank
• Available in penetration, chisel and tiger profiles

Why Buy From Our Factory

• Own foundry, not a trading desk — casting, heat treatment, machining and packing happen in one plant in Zhejiang, China, so we control the hardness curve instead of buying it in.
• 20 years of OEM and ODM experience for bucket teeth and ground engaging tools; your drawings can become a production-ready casting.
• 24-hour technical reply on part matching: send a photo, dimension sketch or machine serial and we confirm the tooth.
• Free sample for fit verification before you commit to a container.
• 12-month warranty against casting defects, with replacement shipped in the next production run.

Inspection Before Shipment

Every batch is hardness tested and dimensionally audited against the drawing. Photos of the packed goods, carton marks and the HRC report are sent to you before the container leaves the plant.

Application

Typical duty: frozen ground and compacted overburden in cold regions, where notch toughness matters as much as hardness.
