Really bad costumer service i return my interculer pipe and take more 1 week

This is a nice set of case studs. The stud by the oil filter was too long. I have to cut about 1/4' off of it. Other than that they worked out great

came in a very timley manner, only wonder is why my other purchas at the same time didnt come in same shipping

it came quick

They look much better than stock and was packaged awesome. Have not completed the truck yet

Good quailty

great looking on my super duty....

great product very quick delevery and the care they put into packaging is top notch

Works great

Great studs

Looks so sick on my 15 6.7 powerstroke. The hot side and cold side went on easy. Noticed a quicker throttle response and the turbo boosting quicker. I’ve had the cold side for a year and no boot problems. I recommend these guys.

I ordered an extra set that I will need to be sending back. Thank you.

Great product. Used for studding mains and heads on 6.0 ls.

Great quality no more worrying about bolts being broke off into the head trying to extract them out. ARP style quality indeed!!

Replaced my ball tubes when I replaced standpipes the socket, made the job easy

Replaced my Ball Tubes and the orings while doing standpipe great decision and good quality socket made the job easy

Installed these standpipes on my 2005 F250 with 170k miles truck runs like new

Part review. Received in a timely manner!

Have used the stud kit from here multiple times. Never have any issues, website is easy to navigate. Highly recommend

These head studs and rocker arms work exactly as advertised. The build quality is top-notch, and you can tell these parts are engineered to handle serious pressure. Everything was individually protected and arrived neatly packaged, which really shows the attention to detail. The installation was straightforward, and the milled rocker pedestals fit perfectly. Highly recommended for anyone looking to upgrade their 12V Cummins build.

They are holding 70 psi of boost with no issues. Everything came neatly packaged and every thread was individually protected. The milled rocker pedestals looked nicer than oem and work perfectly. For the price of the kit and what you get I highly recommend it.

The install was easy! The performance is much better than stock!

These are made with great quality and have been performing well within the forst month of installation.

Great fasteners going to install these once the motor is out .. same quality as arp thanks xotic performance!!

Exhaust manifold stud kit was great!!! Installed so easy.
