About XDP: XDP is a leading retailer, distributor, and manufacturer of top-quality OE, OER, and aftermarket diesel parts and accessories. With over 20 years of experience, we proudly serve the diesel community across North America and Canada.

The XDP LB7 Injector Cup and O-Ring Set XD410 is designed to securely hold the fuel injector in the cylinder head of your 2001-2004 GM 6.6L Duramax LB7 engine. The factory injector cups may experience issues such as seizing, leaking, or corroding, which can lead to over pressurization of the cooling system. This can result in serious problems like blown head gaskets or even catastrophic engine failure.

Replacing the injector cups during a fuel injector installation is crucial for maintaining optimal engine performance. The XD410 Injector Cup Set comes as a direct-fit replacement, ready to install with 8 injector cups and 16 O-rings. Each kit is backed by XDP's 1-year, unlimited mileage warranty. Just one set is required per engine.
