Best Automotive Performance Engine Main Bolts & Studs

ARP 2504202 Stud Kit
Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned, something that won't happen with inferior quality head studs. ARP studs are thread rolled after heat treat, which gives them about 1000 Percent (that's ten times) better fatigue strength than those studs that are threaded prior to heat treat. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force and one that compensates for head gasket compression when the cylinder heads are installed. Thread Rolled After Heat Treat, Which Gives Them About Ten Times Better Fatigue Strength Than Those Studs That Are Threaded Prior To Heat Treat.
Reviews
"With the problems that plague the Ford 6.0L diesel power plant, when it came time to repair the inevitable head gasket failure, installing these ARP head studs was an absolute necessity."
"This product is the reason why many of the 6.0L trucks are still on the road."
"I did remove cab and heads and had the heads checked."
"A must for the Powerstroke 6.0."

Reviews
"Just what every guy or gal needs that has a Chrysler with a HEMI ...was surprised when checking the oil and washer fluid a couple of weeks ago there was just this annoying cap on dip stick tube that said FOR DEALER USE ONLY ...called dealer and can understand they want to make sure you only add OEM fluid as not to void warranty ... heck all I wanted to do was check my fluid level and they wanted me to make an appointment to come in and charge me $49.50 ...no way ... fit perfectly and if and when I need to add proper OEM fluid I will do it myself ... highly recommend and everyone should own a HEMI at least once if or not more times in their life."
"Nice to know the fluid level without having to go to the dealer...Due to it's "newness" the knob was a bit stiff to fully insert in the fill tube where it would lock in place, even with lubricating the "O" ring on the knob."
"simple instructions and easy installation."
"Internet forums are evenly divided on the accuracy vs the factory tool."
"love being able to check my tranny fluid instead of bringing it to a dealer."
