Sinister Diesel

Excellent parts! Super nice people! Ordered several parts for my 6.0 and went straight to the HQ to pick them up and was greeted by staff immediately. I definitely recommend Sinister.

I applied for this company due to the love of vehicles thinking I can make a career with them. I'm young, I have little experience but tons of knowledge from family projects. But they won't call...

This company does bad business. No morals! Do not come here they are a scam! They will not reply to you or give any call backs but will reply as soon as you leave a bad review to try and "fix it"...

Horrible horrible place to deal with. They sell overpriced janky parts and then customer service is just as worse. It's like they know how bad their stuff is and just ignore the complaints.

Horrible customer service. Purchased spider intake kit. Machining was terrible on the air intake side,lip was 1/4 of an inch where the air flows in. I wasn't going to leave a review it took...
