Customer Reviews
Great prices, almost perfect experience!
I was looking for some Volkswagen TDI injectors and Mdd Performance popped up with some amazing deals! Their prices were seriously good, and I almost got my whole order about 20% off with a code. The only tiny thing was that I had to remember to enter the code at checkout, and I almost missed it. Definitely shopping here again and telling all my friends!
Awesome Wheel Spacers!
Needed new wheel spacers for my truck, and Mdd Performance had great prices, though I wish more discounts stacked!
Good experience overall, quick shipping
Compared to some other diesel parts sites like XDP, MDD Performance offers a similar selection but I found their prices quite competitive, especially on exhaust manifolds. I was specifically looking at a set for my truck and the discount I found here was substantial. Placing the order was straightforward, though I did forget to enter my code until I was almost done. Shipping was surprisingly fast, getting my order here quicker than I anticipated. The only minor nitpick is that tracking updates were a little slow to appear, but the product quality seems excellent.
solid place for parts!
ordered a new turbocharger and some switches for my truck, and mdd performance came through again. installation questions popped up and their tech support was actually really helpful, which is a nice change from some other places. wish their site filters were a bit better for finding specific parts, but still a solid experience overall.
Fast shipping, quality filter
Needed an oil filter for my Duramax. Found it easily. Placed the order. It shipped quickly and arrived in good shape. Filter was exactly what I needed. No complaints.
Good parts, delivery mixed
I ordered a set of head studs and a new fuel rail for my Cummins. The ordering process was straightforward on their site, no issues there. Shipping for the head studs was really fast, got them in about 3 days. The fuel rail, though, took closer to 10 days, even though both were supposed to ship together. They arrived in good condition, well-packaged. I had a question about installation for the fuel rail and used their online chat; the rep was helpful but took a while to respond. The parts themselves seem to be of good quality, just what I expected. The head studs went in without a hitch, and the engine's running strong. Overall, happy with the products, just wish the shipping was more consistent.
Reliable for Duramax parts
This is my third or fourth time ordering from MDD Performance, always for my Duramax. This time I picked up a cold air intake kit. Previous orders were for an exhaust system and some glow plugs. They're consistently good with stock and quick to ship. I usually get my stuff within a week, which is pretty standard. Prices are competitive, and I appreciate that the parts always fit right, no surprises. It's why I keep coming back for my upgrades. Never had an issue with a wrong part or bad quality from them.

Share tips, ask questions & help fellow shoppers save more
Anyone know if MDD Performance has a military discount? I'm looking at a new exhaust and every bit helps.
What's the return policy like? Bought a lift kit from another site once and returning it was a nightmare. Just wanna know before I commit.
Trying to decide between a cold air intake from here or XDP. Are the parts from MDD Performance generally genuine or more aftermarket generic stuff?
Anyone bought a tuner or programmer from them? I'm wondering if they offer financing for bigger purchases like that.
Does anyone know if MDD Performance does free shipping? I'm looking at a couple of smaller items but they add up.
