About XDP
XDP is Your Source for All Kinds of Diesel Accessories

Whether you're after engine dress up items, heavy duty gear reduction starters, transmission coolers, or anything in beteween, Xtreme Diesel Performance manufacturers a full breadth of products for your Cummins, Duramax, Powerstroke, or EcoDiesel to keep it on the road and running properly. Nowadays, its hard to find a manufacturer of OE level products that produces at least a little bit of everything. Instead, you're forced to buy your new injectors from one company, the injection pump from another, and then your gasket installation kit from yet another company. By maintaining and constantly growing their catalog of XDP Mfg. branded parts, you're able to stick with a single manufacturer in many instances, adding simplicity and peace of mind that components will work in tandem with one another.

From Exhaust Bolts to Radiators, Xtreme Diesel Power Has Your Needs Covered.

Due to their extensive knowledge in light duty diesel parts, XDP Manufacturing is able to determine shortcomings in factory parts and create a solution to ensure your diesel truck is as reliable as it can be. When it comes time to replace a damaged or worn part on your diesel truck, wouldn't you rather replace it with something that's proven to last, and hopefully last longer than the piece you're replacing? Of course you would! This is where you can trust in XDP's line of electronics and engine parts to keep your truck on the road for the long haul.

Is oil cool gaskets

"Ordered oil cooler Gasket. First delivery date was 3 to 5 days company got payment changed delivery date to 7 to 10 days still didn't come so my truck sat 10 days I finally went to auto parts store and bought one gasket finally came 13 days later and can't get a refund so I'm stuck with a part I'll probably never use DONT BUY FROM THIS COMPANY unless you want your Vehicle to sit parked for long time"

"Worked great, how ever some instructions for the new to 6. 0 world would be helpful instead of a bag of gaskets"

Q&A

Can this be used if my factory pin is still ok for extra insurance
Yes, definitely, and is actually how the pin kit is intended to be used (before a failure).
