ARP 2342503 Stud Kit

Apr nuff said

This stud kit worked perfectly for my 2005 Chevy Avalanche Z71 4x4 LTZ Flex Fuel Truck. I was taking off everything so that I can do an oil pump change on my truck because it had a ticking under the hood that everyone told me was a lifter knock. I wanted to try this and a trunion and push rod upgrade first to see if it would fix the problem. Keep in mind that I decided against changing the lifter and camshaft after checking for metal shavings in my oil pan and once I removed the oil pan and the plate inside the oil pan, I could see the camshaft. I turned it manually and could see that the whole thing was smooth and glassy, so I knew that there was nothing wrong in that area. Plus, there were no metal shavings in my oil pan. I changed the oil pump and this stopped the ticking under my truck (5.3L). I did the trunion upgrade because I heard that after 150,000 miles, these cheap what I call half moon trunions that chevy puts in their LSs tend to wear out and break and end up in the engine, which can do damage inside. I definitely didnt want that, so I changed the trunions to what I call full moon trunions and put a slightly bigger rod in for good measure. My truck is running beautifully. Anyway, this stud kit worked wonderfully.

Well made

Fit perfectly

Didnt really want to buy but went to put a new normal torque ro yield bolt in and it would have been like 350ftlbs. Was just stupid and I was afraid of breaking something. So tosses it aside and got this bolt that was perfect. Make sure you have the socket which I did. Advice is use arp for the LS head bolts as well. Tried to use standards and they were bent and junk. Arp tried and true great stuff.

Would have given 5 stars but $40 for a bolt is riculouis.

ARP look no further. Fit perfectly on my LS3. Note it’s a 12 point use a 27mm 12 point impact socket.

perfect fit excellent quality you get what you pay for

Worked great! Its a 27mm 12 point socket to clear up any confusion, installed last night on my 2004 5.3 harmonic balancer.
