Mack Turbocharger

Every Mack turbo we ship is 100% new — new CHRA, new wheels, new housings. No core deposit, no old unit to crate and freight back, no waiting on credit. Competitors require refundable core deposits; we skip that entirely.

We stock the BorgWarner S300A113 for the E7 and E-TECH, and Holset VGT units for the MP7 and MP8. The E7 is still running in thousands of vocational trucks across North America, and finding a quality new turbo for it gets harder every year — we keep it on the shelf.

The Mack MP8 and Volvo D13 are the same engine under Volvo Group. The turbo hardware is often identical — same Holset HE400VG or HE431VE — but Mack and Volvo assign different part numbers. We cross-reference both catalogs and match by engine serial number so the truck gets the right unit regardless of badge.

Vocational trucks idle more, run hotter at lower speeds, and cycle through more thermal stress than highway tractors. That duty cycle loads VGT nozzle rings with soot faster and wears E7 turbos harder. We understand the failure patterns on both platforms and help shops diagnose before ordering.

Mack vocational fleets — refuse haulers, concrete companies, municipal truck pools — replace turbos on a schedule, not one at a time. Pricing is structured for that volume: consistent wholesale cost, US inventory, and the same ESN verification on every unit. See the wholesale program.

One-year warranty on every turbo, handled by our US team. On the MP8, we walk through the VGT root-cause check — oil condition, charge-air leaks, EGR soot load — before install so the new unit does not inherit what killed the old one. On the E7, we check oil supply and boost plumbing. Details on the warranty page.
