Heavy-Duty Alternators & Mounting Components for Diesel Engines
Alternators are essential for generating electrical energy that powers all major systems in heavy-duty trucks, commercial equipment, agricultural machinery, and construction engines. Our catalog includes truck alternators, mounting brackets, alternator housings, tension supports, and OEM replacements for top engine platforms such as Cummins ISX, ISB, ISL, QSM, QSX; Caterpillar C13, C15; Detroit Diesel DD13, DD15, Series 60; Volvo D12, D13; Paccar MX13; John Deere 6068 and many more.
Why a reliable alternator matters
A high-quality diesel engine alternator ensures stable battery charging, consistent voltage output, and dependable operation of every electrical system – from lighting and sensors to engine control modules and safety electronics. A failing alternator can cause dim lights, weak cranking, battery drain, warning indicators, and sudden shutdowns, which are especially dangerous for long-haul trucks, vocational vehicles, and equipment working under continuous load.
When choosing a replacement alternator or support bracket, consider:
- compatibility with your specific engine model and OEM number,
- amperage rating (e.g., 120A, 160A, 170A+, high-output brushless units),
- mounting configuration: pivot-mount, pad-mount, saddle-mount, tension-frame,
- environmental demands such as vibration resistance, corrosion protection, and temperature stability.
Reliable power components engineered for durability
Our selection includes both new and refurbished OEM-grade alternators, along with a full range of support brackets and mounting hardware. Designed for extended service life, these components feature reinforced housings, sealed bearings, and high-efficiency windings that maintain stable performance even in extreme operating environments. Whether you’re replacing a damaged alternator bracket, upgrading a brushless alternator for higher output, or restoring an entire charging system, each product ensures consistent power delivery and long-term reliability.
