Do you sell genuine or aftermarket diesel injectors?
Both. Maxzz Diesel stocks genuine Bosch, Delphi and Denso injectors and pumps with the original manufacturer part numbers, plus aftermarket options from suppliers with known origin. For the most common part numbers you can quote both and choose between original equipment and the best cost.
How do I find the right part number for my injector or pump?
Read the number on the injector or pump body, for example a Bosch 0445 code, and search it in the quote page. You can also pick the make, engine and model years. If you are not sure, send the number and the engine and our team confirms the part before it ships.
Which engines do you cover?
Light duty pickups and heavy duty engines: Cummins 5.9 and 6.7, ISX15 and XPI, Duramax 6.6 from LB7 to L5P, Ford Power Stroke 6.0, 6.4 and 6.7, Detroit DD15 and Series 60, Caterpillar C7 to C15, Volvo D13 and Paccar MX13, among others.
Do you sell repair parts to rebuild injectors?
Yes. Nozzles, needles, control valves, solenoids, seals, o-rings, shims and connector tubes from Bosch, LEAD and Fratelli Bosio, plus Robiel tool sets and ISO 4113 calibration fluid, so an injection lab can rebuild and test with parts from one supplier.
