Easy to order. Fast delivery. Had an issue with one of our parts. Made one phone call and a replacement part was in route with a return label to send damaged one back. Great customer service. Definitely will be buying from them again.

Caterpillar Injector FAQs

Start with the part number on your current injector and your Caterpillar engine model. Providing your engine serial number can also help our team verify the correct application. Call STR when you are unsure, and we will help match the correct injector before you order.

STR carries injector options for Caterpillar applications including the C7, C9, C13, C15, C16, 3406E and ACERT platforms. Additional products are available for engines such as the 3408, 3412, 3508 and 3512. Availability varies by part number.

Each remanufactured Caterpillar injector is professionally cleaned, rebuilt, calibrated and tested to support proper fuel delivery and cylinder balance. This process helps identify injector performance issues before the part is shipped.

STR offers several Caterpillar injectors individually and in sets of six. Replacing one may make sense when testing identifies a single failed injector. A complete set may be the better option when multiple injectors are weak or the engine has high operating hours.

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.
