If you work on Detroit Diesel Series 50 or 60 engines, this injector height gauge kit is a must-have. Setting the injector height correctly is crucial for proper fuel timing—get it wrong, and you’ll have power issues, rough idling, and bad fuel mileage.
The kit includes five precision-machined steel blocks: 78.2mm, 78.8mm, 80.3mm, 81.0mm, and 82.1mm, plus a knurled handle that lets you use them at a 90-degree angle in tight spaces. They’re made from high-quality steel, so they’re durable, corrosion-resistant, and won’t deform.
This tool replaces OEM part numbers like J-42749, J-45002, and others. It’s compatible with various DDEC models and years (check the description for specifics). Comes with an 18-month warranty and a 30-day money-back guarantee. So if you’re tired of guessing, grab this gauge and get your engine running smooth again.
