ARP 247-4202 Stud Kit: Boost Performance and Reliability Review

Installation is easy. Takes more time than you think. It helps if you have a friend to help with the train when your hands get tired. Keep the speed!

2004 Dodge 2500. Works amazing. I regularly press around 30psi. Did a new head gasket and installed it. No leaks so far. I also used an arp install connection.

Stronger than stock! Fits great on my 2003 5.9 24 Vavle Dodge Cummins! Had to modify rocker box to go down, almost all center lugs touched aluminum so clearance with a ridge was a must!

Excellent. As advertised. Have at least some mechanical flair, and the installation will go smoothly. Go slow, take your time. In any case, I highly recommend getting a creeper from the top. I injured my chest badly. Also, have a large enough torque wrench. I'm 22 1/2" tall and my arm was very tired afterwards.

ARP is second to none when it comes to fasteners. They worked great on my Cummins 6.7. Installation is a small job.

I also replaced the rocker arm seal with a new one. If you are a non-commercial Cummins owner (Dodge Ram etc) you can register at https://quickserve.cummins.com and find all the engine information…

Instructions for use are included with the studs. I would suggest going to Glacier Diesel for a more detailed step by step guide (PDF available). As for the cleats; everything works as it should and lasts better! I've always hesitated with stronger tunes on my programmer. These stilettos gave me peace of mind. The head stays where it should be and my coolant level is fine. It took me almost all day to install. In short, I recommend them to anyone looking for extra insurance when putting more…

I have a 2007 Dodge Ram 2500 with a Cummins 6.7L engine. I wish I had rebuilt these rivets years ago, but I didn't. The head gasket failed at about 98,000 miles. I hired a mobile diesel engine technician to come to my house and help me change the gasket and install the studs. As a result, I also changed the valves, so the top part of the engine is like new. There was a lot of work! This mechanic torqued the nuts to 135 ft-lbs, which is 10 ft-lbs higher than what Cummins had at the factory. He…
