Nissan Diesel UD Rear Brake Drum OE 43207-90118M Truck Brake Drum Casting

Product Specification

Premium Rear Brake Drum for Nissan Diesel UD Trucks - OE 43207-90118M | High-Performance G3000 Casting

The OE 43207-90118M Brake Drum is a mission-critical safety component engineered specifically for the heavy-duty rear axles of Nissan Diesel (UD Trucks). Designed to meet or exceed OEM performance standards, this brake drum is built to handle the high-torque and intense thermal loads of commercial freight, logistics, and construction transport.

Crafted from high-carbon G3000 grey iron (HT250), our 43207-90118M model undergoes rigorous precision machining and dynamic balancing. This ensures exceptional heat dissipation, preventing brake fade and surface cracking even during prolonged downhill braking with heavy payloads. For fleet managers and workshop owners, this drum offers an ideal balance of OEM reliability and aftermarket cost-efficiency.

Vehicle Compatibility

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

Nissan Diesel (UD Trucks): CW, CWA, CWB, and CKG series models.

UD Quon: Selected rear axle configurations.

UD Big Thumb: Heavy-duty 6x4 and 8x4 tractor and tipper models.

Specialty Chassis: Compatible with certain UD-based fire trucks and concrete mixers.

Expert Tip: To ensure a perfect fit, please cross-verify the pilot diameter (250mm) and bolt circle (300mm) with your current vehicle's hub specifications.

FAQ (Frequently Asked Questions)

Q1: How do I know if my UD Truck needs a new 43207-90118M brake drum?

A: Common signs include brake pulsations (judder), loud squealing noises, or visible blue spots and cracks on the drum surface. If the internal diameter exceeds the maximum wear limit (usually marked on the drum rim), replacement is mandatory for safety.

Q2: Is this brake drum compatible with all UD Big Thumb models?

A: While it fits many Big Thumb models, some axle variations exist. Always check your hub pilot diameter (250mm) and bolt circle (300mm) against our Technical Specifications table to ensure compatibility.

Q3: Why choose G3000 grade material for this brake drum?

A: G3000 (GG25) is the industry standard for heavy-duty braking. It offers the perfect balance of tensile strength and thermal conductivity, which is essential for heavy trucks like Nissan UD that operate in mountainous or stop-and-go environments.
