Every engine build has a different goal. Whether you need a dependable replacement or a more serious build package, these levels help guide the conversation and point you toward the right starting place.
Stock
A dependable replacement engine option built to restore reliability and stock-style performance for customers who need a solid starting point.
Stock Plus
A step above stock for customers looking for a stronger overall package while staying close to a stock-style replacement foundation.
Stage 1
A stronger performance-oriented engine package for customers needing more than a stock-style build and planning around added power and supporting upgrades.
Stage 2
A more serious build level for customers with bigger performance goals where the engine package, supporting parts, and overall combination all matter.

Built With Real Diesel Knowledge
More Than an Engine Assembly Line
Industrial Injection engines are backed by decades of diesel experience across machining, fuel systems, turbochargers, and complete engine builds. That knowledge matters when the goal is reliability, performance, and the right combination of parts.
Engine Machining
In-house machining and preparation help create the foundation for a better engine build.
Fuel System Knowledge
Our fuel system experience helps us understand how injectors, pumps, and supporting parts affect the complete build.
Turbocharger Experience
Turbo knowledge matters when an engine is being matched to airflow, power goals, and real-world use.
In-House Assembly
Each engine build depends on the right parts, process, and attention to detail from start to finish.

Freight & Core Return Support
Heavy Parts Need a Better Shipping Process
Engines are not small-box parts. Industrial Injection helps coordinate freight, delivery details, and core return logistics so the process is easier to quote, explain, and manage from purchase to delivery.
From delivery planning to core return coordination, our freight process is designed for large diesel components that need more than a standard shipping label.
Coordinated Freight
Qualifying engines ship through our coordinated freight process to help simplify delivery and reduce guesswork.
Delivery Options
Choose the delivery option that fits your location, including commercial delivery or residential/liftgate service when needed.
Core Return Support
When a core applies, we help make the return process clear so you know what needs to come back and when.
Heavy Part Handling
The process is built around engines, cylinder heads, and other diesel components that require proper freight handling.
