The fact that i didnt have to call customer service says it all. Parts came on time, and were exactly in a package that made sense and wasnt overpriced. Hard to do durring a pandemic. Other parts i ordered from other shops i still have yet to recieve.

Product Choice

Because mahle gaskets are the best out there, and ARP studs is the number one brand for studding a head.

Company Choice

The head gasket kit i needed had everything i needed including studs and was easily found using a simple google search

My overall experience with sinister diesel was a great one! From the easy access to parts, to the world of scripted purpose and use for those parts, to the easy checkout, and lastly to the quick delivery. No issues and would love to shop here again!

Because of great product reviews!

It’s a highly suggested part that is needed for the 6.0 liter Powerstroke.
