What our customers say

This place is awesome! I tried ordering from 3 different places with nothing but problems before I found these guys. Great quality turbo, great price, and fast shipping. What more can you ask for?

excellent communication, committed to an aggressive timeline and delivered. part looked as good as new, i was shocked. this was a rebuild for a volvo penta marine engine. very capable shop that i will recommend around my marina.

I called around 15 places trying to find someone that does a turbo rebuild. This was the only place I could find that works on Turbos instead of just replacing them. I checked out many of their reviews and made the decision to go with this company to rebuild my 2014 Dodge ram turbo. Come to find out I had some aftermarket parts. They went ahead and upgraded to the original Cummings Turbo and actuator. The price was unbeatable. I feel they did some extra things like flushing, the coolant and replacing my air filter as well. The truck is running really good and I have nothing but positive things to say about my experience and working with Samperio.

Cummins Injectors FAQ

How do I find the correct Cummins injector for my engine?

Use the part number from your current injector and your Cummins engine model or serial number. If you’re unsure, contact STR and we’ll help match the correct injector before you order.

Which Cummins engines do you carry injectors for?

STR carries injector options for popular Cummins engines including ISB, ISL, ISX, ISX15, N14, M11, L10, and ISM applications. Availability varies by part number and engine serial number.

How are STR Cummins injectors rebuilt and tested?

Each remanufactured Cummins injector is cleaned, rebuilt, calibrated, and tested to verify proper fuel delivery and performance before shipment. This helps ensure reliable operation when the injector is installed.

Should I replace one injector or the complete set?

STR offers Cummins injectors individually and in complete sets. A single injector may be enough if only one has failed, while a full set is often recommended when multiple injectors show wear or the engine has high operating hours.

Are Cummins injectors covered by a warranty?

STR provides a 12-month, unlimited-mileage limited warranty on its products, including electronic injectors. The warranty covers qualifying defects in materials or workmanship but excludes issues such as contamination, improper installation, misuse or unauthorized repairs. Installation by a certified technician is strongly recommended.
