About This Holset HE300VG Rebuild Kit (2018 and Earlier)

The Holset HE300VG is the variable geometry turbocharger used in the Cummins ISB 6.7L diesel engine found in Ram 2500 and 3500 trucks from 2013 through 2018. It is one of the most common VGT platforms in the light-duty diesel market. While built to last, years of heat cycling and extended oil change intervals will eventually wear the internal bearings and seals — particularly the thrust bearing, which is the most loaded component in this application.

Important: This kit is designed for the 2018-and-earlier HE300VG. The 2019+ redesign uses different internal dimensions and requires the separate 2019 and Up kit. Verify your turbo part number before ordering.

What Is Included

• CNC-machined journal bearings — matched to pre-2019 CHRA dimensions
• Upgraded thrust bearing assembly
• Compressor and turbine piston ring seals
• O-rings, gaskets, and snap rings

Upgraded Thrust Bearing — Why It Matters Here

The HE300VG thrust bearing absorbs the axial loads from gas pressure on the compressor and turbine wheels. Extended oil change intervals or any idle periods with degraded oil accelerate wear specifically on this component. The upgraded bearing in this kit uses a harder alloy with improved surface finish to outlast the factory specification part significantly.
