This turbocharger is designed as a bolt-on upgrade for compatible Caterpillar 3406E and C15 applications.

CAT engines were produced with numerous turbocharger, exhaust manifold, and engine configurations. Always verify your existing setup and turbocharger fitment before ordering.

Why Choose the 1.45 A/R Housing?

The larger 1.45 A/R turbine housing is intended for applications where reducing exhaust restriction and drive pressure is a priority.

Compared with a tighter turbine housing, the larger 1.45 A/R housing allows the turbine side to flow more exhaust gas. This can help reduce excessive drive pressure at higher engine speeds and is particularly beneficial on engines that spend significant time under load at highway RPM.

Assembled & Balanced in the USA

This Momentum Worx turbocharger is assembled and balanced in the USA to provide a high-quality performance turbocharger for demanding Caterpillar applications.
