Trailer brake failure is not an option. That's why you need air assemblies that are resistant to the kinks and weathering that can reduce the ability of your brakes to do their job.


When it comes to your trailer connections, look for the full line of Alliance Truck Parts coiled and straight air assemblies. Each durable assembly is built to last with rugged materials and a design that helps ensure kink-free, leak-free operation.



Covering a wide range of applications, Alliance Truck Parts alternators meet or exceed OEM specifications and are rated for the higher temperatures found in the latest emissions compliant engines.

They are engineered of all-new parts for real durability and utilise a solid lead frame, creating a single, solid connection to all of the internal diodes as well as improving shock and vibration resistance.

Alliance alternators are available with pad mount or J180 mount options. Amperage ratings range from the compact 444 model’s 150 Amps, up to a full 210 Amp rating.
