Rebuilt Cummins Engine Sales is a specialized engine supply division of RS Industrial Engines, focused exclusively on delivering high-quality replacement diesel engines for construction, industrial, material handling, municipal, mining, oilfield, marine, and power generation applications throughout North America.
As part of RS Industrial Engines, we operate with structured sourcing, technical evaluation, and operational standards designed to support contractors, fleet managers, equipment dealers, and industrial operators who require dependable power solutions with minimal downtime.
Our primary offering consists of brand-new surplus diesel engines sourced through established industrial supply channels. These complete engine assemblies provide customers with production-ready replacement platforms at pricing typically below traditional OEM dealer networks. In select cases, professionally remanufactured engines may be available; however, our core focus remains on supplying new complete engine platforms whenever possible.

DOWNTIME MATTERS
In construction, mining, municipal operations, logistics, and energy production, downtime directly impacts revenue and project timelines. Our role is to provide reliable replacement engine solutions that restore operational capacity efficiently and responsibly.
