Long wait Waited more than a month and a week for my order. Never received any notice that it would take so long. When I called they had no idea. And said they would call me back in which they did actually and said a couple more weeks. After they already had my money from day one. It doesn't seem right to me to take the most the without fulling the order first.

All about Money, not honest company All about money , found company not to be honest. Just make sales. Called in to find what I needed for egr dpf kit ,and what I needed to make work as programming what has been deleted. Told me /- for which I ordered online to save on taxes and freight per agent. Bought dpf egr delete & programmer bully ? After spending another 500.00 remove egr,dpf,exhaust system , I find out this was not legal removing emissions system. On top of that , agent wants me to send back programmer at my extra cost. Shipping plus restocking fee. My dodge is now not running. Thank you for your dishonestly

Good parts but poor service 3 weeks later and I still have not received my order have called twice and same old run around everytime I don't think I'll be buying anymore stuff from them

Damaged part was delivered to me. I ordered a front grille assembly for my Ford Superduty. Initially, the part was delivered damaged. The price of this item was around $300.00 delivered. The part took about a week to arrive at my residence, which is what I expected. Attempting to return the damaged part back to MKM was a nightmare, because UPS tried to charge me over $80.00 to ship the part back to the facility. Luckily, MKM Customs was able to prepay the shipping. However, this seemed to take a while, as this is the method that should have been chosen anyways. I was also unhappy with the way I was treated on the phone when the receptionist attempted to blame me for the existing damage on the grill. Although I am sure that many others have success with this company, this is one instance that may have slipped through the cracks. Some additional care with packaging, along with an improvement in handling customer complaints are sure to improve the overall quality of the customer's experience in the future. In the end, MKM did the right thing and sent me a nice, undamaged grill. However, it seemed like a big hassle and a lot of money for a shiny piece of plastic made in Taiwan.

Great place to buy diesel parts for your truck! Sinister MKM makes and sells high quality parts for diesel trucks. I've spent thousands of dollars with them and will continue to do so when needed. Shipping is kinda slow (and not cheap), but website is easy to use, and staff is fast and friendly! In my opinion, Sinister MKM should be every diesel truck owner's first place to shop for performance upgrades! I love these guys!!
