Part No. 439-1716 is an original Cat® GET bucket wear-resistant component - a bolt-on half-arrow bucket edge protector.

Manufactured under Caterpillar's unified global high-standard precision production process with tight tolerance control and industry-leading forming accuracy, it is specially engineered to match the working conditions of Cat wheel loaders. It delivers comprehensive defense against continuous impact and abrasion from hard materials such as ore, sand, gravel and muck, forming a long-lasting wear-resistant shield for bucket cutting edges.
All GET wear parts are custom-developed based on the structural characteristics of Cat equipment for perfect fit. They consistently provide heavy-duty round-the-clock protection and drastically reduce bucket wear, serving as a core genuine wear part that boosts equipment durability and cuts operation and maintenance costs.

This component is designed to add reinforced protection to the bucket base edge and expand coverage over gaps between tooth holders. It completely prevents materials from scouring and grinding the base metal near tooth holders, fundamentally eliminating premature thinning, cracking and damage to local sections of the base edge. Its signature streamlined half-arrow profile has been validated across countless job site conditions to optimize material cutting angles and greatly enhance digging penetration. Meanwhile, it improves the bucket's capacity to gather and hold materials, cutting down travel cycles and directly raising overall job site productivity.
The protector is integrally cast from specialized DH-2 wear-resistant cast steel with stable metallographic structure. Its hardness barely diminishes under long-term heavy loads, delivering far longer service life than ordinary wear parts and enabling loaders to sustain rated working performance at all times. Opting for genuine Cat Part 439-1716 maximizes the protection of your construction machinery investment, minimizes downtime losses caused by bucket repair and replacement, and achieves long-term cost reduction and efficiency improvement.

Core Product Features
Bolted fastening installation; no welding required for fast disassembly and replacement, shortening maintenance downtime
Full coverage protection for the main bucket base edge to significantly extend the service life of bucket base metal
Separates tooth holders from direct material friction, effectively prolonging tooth holder service life and lowering replacement frequency
