Swap with OEM

Exhaust components for Komatsu

When changing Komatsu exhaust parts, upgrade to premium parts for long-term performance. Aletek manufactures premium exhaust upgrades that enhance OEM designs. Quality Australian fabrication and in-house design are key to our product designs. If you have an exhaust problem, we’re here to help.

Exhaust Pipes for Komatsu

Several types of exhaust pipes with flanged ends are available, including straight pipes and elbows. In the pipe construction process, we use 2mm reinforced steel. Our logo badges point in the direction of airflow to facilitate installation. In dual-wall pipes, vent ports are strategically placed to protect the inner wall.

Mufflers & Tailpipes for Komatsu

To protect against corrosion and abrasion, our mufflers are constructed with 3mm steel and powder coated for high-temperature applications. A logo badge indicates the direction of airflow. Our brackets and mounting plates are reinforced for strength.

Aletek Pipe Bellows

Aletek carries V-band clamps and hardware for installation to support our Komatsu-compatible exhaust systems. As well as exhaust components and full exhaust kits, we also carry general components, gaskets and straps.

Clamps & Install Hardware

Aletek air intake upgrades replace the OEM system between the air filter box and the turbo. 830E and 930E upgrades are part of our bespoke solutions. We provide heavy-duty clamps for all intake connections. In our systems, dust is less likely to enter turbos or engines.

Komatsu Excavators

With Aletek exhaust components and kits, you can increase the productivity of your Komatsu mining excavators. We offer OEM exhaust systems such as a PC3000-6 upgrade. There is also the option of custom designs, like our PC4000 exhaust silencer package.

Providing Komatsu haul truck exhaust upgrades is what we do best. We offer OEM replacement exhausts, dual-wall upgrades and sound suppression solutions for the Komatsu 830E and 930E. In addition, we provide exhaust upgrades for smaller trucks like the HD785 and HD1500.
