G3000 Casting Rear Brakes Drum OE 43207-90107M Performance Brake Drums

Product Specification

Heavy-Duty Rear Brake Drum for Nissan Diesel UD Trucks - OE 43207-90107M | Premium G3000 Casting

Product Overview

The OE 43207-90107M Brake Drum is a premium safety component engineered specifically for the rear axle systems of Nissan Diesel (UD Trucks) and Isuzu heavy-duty commercial vehicles. Designed to meet or exceed OEM specifications, this brake drum provides consistent stopping power and maximum durability under extreme load conditions.

Manufactured from high-carbon G3000/HT250 grey iron, our 43207-90107M model features optimized wall thickness for superior thermal management. Each unit is 100% dynamic balanced to eliminate vibration, ensuring a smooth ride and protecting wheel bearings from premature wear. Whether for long-haul logistics or construction site operations, this brake drum is built to perform in the harshest environments.

Vehicle Compatibility

This brake drum is a direct replacement for several Japanese-engineered heavy truck series:

Nissan Diesel (UD Trucks): CW, CWB, CWA series, and UD Big Thumb heavy-duty models.

UD Quon: Specific rear axle configurations.

Isuzu Giga / C-Series: Selected heavy-duty models (please verify via technical dimensions).

Industrial Trailers: Heavy-duty axles utilizing UD-compatible hub patterns.

Technical Tip: We recommend checking your current drum’s pilot diameter and bolt circle to ensure 100% compatibility before installation.

Key Benefits

Optimized Thermal Dissipation: Advanced casting technology prevents "heat checking" and surface cracking during prolonged braking on steep gradients.

Precision Dynamic Balancing: Every drum is factory-balanced to eliminate vibration, ensuring driver comfort and reducing wear on the hub assembly. 

OEM Geometric Accuracy: Machined on high-end CNC equipment for a "bolt-on" installation, reducing maintenance downtime.

Corrosion Protection: Each drum is finished with a protective anti-rust coating to ensure it remains in pristine condition from our warehouse to your axle.

Reduced Cost Per Mile (CPM): High-grade wear-resistant material extends the replacement interval, lowering the total operating cost for fleets.

Frequently Asked Questions (FAQ)

1. Which vehicle models is the 43207-90107M Brake Drum compatible with?

The 43207-90107M Brake Drum is a premium replacement part specifically designed for Nissan UD Trucks, including the UD CWA, CWB, and early Quon series. It is manufactured to meet the exact dimensional and performance standards of Japanese heavy-duty axles. To ensure a 100% correct fit, we recommend verifying the 10-hole mounting pattern and checking the internal diameter against the original part number 43207-90107 or 43207-90059.

2. How does the G3000 material handle the thermal stress of heavy hauling?

Our 43207-90107M drums are cast from high-grade G3000 Grey Cast Iron. This high-carbon metallurgy is essential for thermal conductivity, allowing the drum to absorb and dissipate heat rapidly during sustained braking on steep descents or heavy-traffic hauling. This prevents brake fade and resists the formation of surface "heat checks" (small radial cracks), ensuring the structural integrity of your Nissan UD braking system.

3. Does the 43207-90107M Brake Drum come factory dynamically balanced?

Yes, every 43207-90107M unit undergoes rigorous precision dynamic balancing before leaving the factory. For heavy-duty commercial vehicles, even a minor centrifugal imbalance can lead to significant chassis vibration and "pedal pulsation." By installing a pre-balanced drum, you protect your wheel bearings, hub seals, and tires from premature wear, reducing the total cost of ownership (TCO) for your fleet.

4. What is the safety wear limit (Max Dia) for the 43207-90107M?

For maximum road safety, the Maximum Diameter (Max Dia)—the safety wear limit—is cast or stamped on the outer rim of the 43207-90107M. During routine maintenance, the internal diameter must be measured; if it has reached the Max Dia limit, the drum must be replaced immediately. Using a drum beyond its wear limit reduces its ability to dissipate heat and increases the risk of structural failure under emergency braking pressure.
