Rated for higher temperatures in 2007 and 2010 EPA emissions-compliant engines is a new line of heavy-duty alternators from Alliance Truck Parts. The product line covers a wide range of applications that meet or exceed current OEM specifications with pad mount or J180 mount options. Amperage ratings range from the 444 model’s 150 amps up to a full 210-amp rating. Temperature ratings for all models are 125° C with the exception of the 444 model, which carries a 110° C rating.
Other features for various models in the new Alliance alternator line include a redesigned solid lead frame rectifier with a welded diode assembly, a sealed brush box, case ground, heavy-duty front and rear bearings, a dual internal fan, and an e-coated housing for corrosion resistance. All Alliance alternators utilize a solid lead frame, creating a single, solid connection to all of the internal diodes.
