These folks know customer service. They went above and beyond to help get my equipment back online. I highly recommend them!

I just bought a used 2018 Mahindra Roxor. I couldn't find parts. Diesel Freak had what i needed and i learned a few things about my new Roxor that i didn't know. They have great recommendations on accessories and parts. i bought a backseat, hubs, a leveling kit, and some maintenance items. They shipped them out FAST! No worries with delays from Covid for DieselFreak! Get your FReak on!

They send you poorly manufactured components then when the wire breaks off they want almost as much to replace the adjustment knob as you paid for the whole power wire set up. I was actually shocked they wasn't gonna send me a replacement for their poor craftsmanship. Don't buy from here the quality and customer service is horrible. UPDATE the part that was defective is $15 or less on several websites. These jokers wanted $80 + shipping.

I just got off the phone with Wade from Diesel Freak. First of all, I could not be more impressed with their service, product line, and knowledge ( I received nothing in return for doing this!) Second, as the old saying goes do a good job and they will tell 10 people, do a bad job and they will tell 100. Well the folks at Diesel Freaks did an incredible job, so I am telling everyone. I got my ECU back and installed today and it felt like I went from a '76 Chevette to a 2020 Corvette, WOW what a difference. I Could not be happier. Thank you, Wade and everyone at Diesel Freak.
