2004.5 5.9 Cummins head studs

Product was received in good manner. Have yet to install, will update review after I put the studs to the test😼

Good customer service!

Great product, had everything needed for the install with good directions. If you’ve got any common sense then you can read the directions with no problem. Hard 2k miles and no problems yet lol

Love the product works great

I don’t like not having a choice of what carrier company to ship my product

Fantastic head studs

I have installed two sets of these and I will say I am very happy.. the product was well packed with thread protectors on the studs. And the great thing is they have the sockets needed to do the Inatall.

12V 5.9L Dodge Cummins Head Stud Kit 1989-1998


6.7 Cummins head studs

Everything was packaged perfectly! In the instructions they don’t have proper numbering it states 1-18 when it’s 1-26 just be sure watch that not leave your studs loose. Overall great product. I want 135ft lbs instead of 125ft lbs because I didn’t want to do a hot torque. I’ve done this on multiples of trucks with no issues

Un used

The kit said 2004+ same size bolts. I didn't know I did not have same size bolts until after I got the truck apart. They are incorrect part and now I have to figure out how to return them

Great product

This product was everything described and was shipped very fast

Head stud kit

Just wish you would have put some torque specs in with the stud kit.

Outstanding product

Studs look and feel good. Quailing is definitely there. Only complaint is I did not receive correct hardware (Nuts) for the studs. I got 10 Nuts that were correct and the other 16 were not even close to the right size. My project was delayed and had to contact Xotic to get the right hardware. Once I sent the order number and stated my issue they sent me new Nuts right away. Good company. Upset I’ll be out of a truck until they come in.


Fast shipping great value and great product this is the second time using them and they are great highly recommended to anyone looking for head studs

6.6L Chevy Duramax Head Stud Kit 2001-2016

Good quality for a unbeatable price

Don’t drive the truck much but when it is being used I run the truck hard and push it to redline all the time and they have held up wonderful, self install is a little tricky if you don’t have the right tools for the job but can definitely be done
