Premium Heavy-Duty Brake Drum 7358 | 15" x 4" Rear Brake Drum for Trucks & Trailers

Product Overview

Our 7358 Brake Drum is a high-performance, precision-engineered solution for heavy-duty trucks and trailers. Designed to meet and exceed FMVSS-121 standards, this drum is specifically balanced for rear-axle applications.

Constructed from high-carbon G3000 grey iron, the 7358 model provides excellent heat absorption and dissipation, which is critical for preventing brake fade during heavy hauling. Whether you are operating a Class 7 or Class 8 truck, or a standard commercial trailer, our 7358 drum offers the structural integrity and reliable friction surface your fleet requires for maximum safety.

Key Benefits

Superior Heat Management: The high-mass design acts as an efficient heat sink, maintaining stable friction levels even under high-cycle braking.

Machined to Perfection: Each drum is CNC-machined to ensure perfect concentricity, reducing "pedal pulsation" and uneven lining wear.

Increased Durability: Our casting process minimizes microscopic porosity, leading to a higher resistance against thermal cracking (heat checking).

Ready to Install: Pre-balanced and treated with a light anti-corrosion coating, saving your technicians time during installation.

FAQ

Q1: Is the 7358 drum suitable for steer axles?

A: The 7358 is primarily designed for rear drive axles or trailer axles that require a 15" x 4" braking surface. Always check your vehicle service manual for axle-specific requirements.

Q2: Does this drum require additional balancing?

A: No. Our 7358 drums are dynamically balanced at the factory. You can install them directly "out of the box."

Q3: How do I know if I have a 7358 or a different 15-inch drum?

A: The most important measurements are the Pilot Diameter (8.78") and the Overall Depth (8.81"). Please compare these with your existing drum or contact our tech support.
