Customer Reviews
Good deal on exhaust system
I was looking for a new Exhaust System and saw they had a decent price. I checked a few other stores, but with their free shipping within Canada, it ended up being the best value for me. Didn't see any specific discount codes at checkout, but the base price was good enough. The system arrived in good shape. Saved me a bit compared to buying local, so that's a win. Felt like a solid purchase.
Decent parts, slow tracking update
I bought some Suspension Lift Kits for my truck. The parts themselves seem high quality, no complaints there. Everything was in the box and well-packed. Shipping was okay, it arrived in 6 days which is acceptable. My only minor issue was the tracking info took a day or two to update after I got the shipping confirmation. Just made me a little antsy waiting. Customer service was responsive when I emailed to ask about it. Overall, a good experience, just wish the tracking was more immediate.
Back for more parts
This isn't my first time ordering from Canadian Diesel Online. I've bought Exhaust Systems and various filters before. This time I needed a Transmission Upgrade. Consistency is key for me, and they delivered again. The part was exactly as described and fit my Duramax perfectly, just like previous orders. Shipping was consistent with past experiences, taking about a week to Nova Scotia. They're reliable, which is why I keep coming back for my diesel parts.
Air intake and filters order
I ordered a Cold Air Intake and some Fuel Filters for my Cummins. The website was easy to navigate, found what I needed fast. Shipping took about a week to get to me in Alberta, which was fine. Packaging was good, everything arrived without damage. Installation was straightforward with the included instructions. The intake fit perfectly, and the filters were correct for my truck. Had a small question about a specific torque spec, so I used their online chat. Support was quick and helpful, got the answer in minutes. Overall, a smooth experience from start to finish.
Turbocharger arrived quick
Needed a new Turbocharger. Ordered it. It shipped out fast. Got it in 4 days. Fit perfectly. No issues. Happy with the purchase.

Do they ever do a military discount? My buddy told me some places do but I can't find it on their site.
Thinking about getting a lift kit but worried about returns if it doesn't fit right. What's their return policy like for performance parts?
How fast is shipping generally? I'm in Vancouver and need a new exhaust system for a trip coming up soon.
Hey, looking to grab a new tuner for my Duramax. Are their parts actually legit, like from S&B or Flo~Pro, or are they knock-offs?
Are their prices in USD or CAD? Just wanna make sure I'm not doing the conversion in my head wrong lol.
