These are just as good for your builds as ARP fasteners , they are everything that they were discribed to be and then some

First things first they offered me $20 to write this review in the form of a refund for my purchase Thought that was important to point out !This is my second set. I have installed on two different trucks. Overall very happy but time will tell if it deserves five stars so far so good 6BT 12 Valve Cummins

Very pleased with packaging and presentation when they arrived shipping is quick comes with everything you need and they are high quality I will be purchasing from Xotic again

Looks great hadn't installed yet for next engine build want the reliability of not having blown stand pipe seals will update when installed looks promising

Is what I ordered And came super fast which was nice

Better than stock

Shipped in one day only payed 8 dollars for shipping. 300 miles later still working and a fixed high pressure oil leak.

Installed pipe and throttle response is much better!

Assembly looks like quality parts. They are very well made and have a smooth, professional look. I am installing these on a spare engine I will be putting together in the next few months.

This was a great kit came with everything you needed to do the job I ran into a small issue because mine was a late 97 12v my main bolts were 12mm instead of 14mm I got ahold of them and they got me the right ones sent over asap great customer service

These actually perform quite good. I'm surprised how easily they torque down but no issues as of yet

Nice upgraded direct replacement rocker arm set. I believe these still have needle roller bearings but as you can see in the pictures they are better protected. I installed them in an LS chevy tahoe with a stage 2 cam and LS7 lifters. They worked flawlessly. I was blown away by the quality for the price, I wasn't expecting them to be this nice.

This seems to be a very well made set. Measuring them with a caliper they are exactly the same ratio as the stock units and seem pretty beefy. The trunions are smooth and look exactly like the more expensive "kits" on the market and honestly probably all come from the same place. I will be running these on a high lift cam at fairly high rpms so I will see how they hold up. I think this is a very good budget upgrade over stock.

If im remembering correctly iv gotten headstuds from this brand before and those were really nice. This kit was just the same high quality rockers and unlike another kit i had where i had to put it all together these were drop in ready. Its not alot of frustration to put the kits together but to know that someone else whos done 1000s of these vs myself thats done a set. quality checked them. it does make me alittle less nervous besides if it breaks wasnt my fault haha. Really easy install everything was there and they work great.

This kit is very well put together and feels solid right out of the box. The rocker arms and trunnions are cleanly machined and the pre-assembly makes installation simple. Everything fit without issues and the upgrade adds peace of mind over stock parts. For the price it is a durable and reliable option that should hold up well in performance builds, making it a good value for anyone working with an LS platform.

High quality and very competitive price vs doing the trunion bushing upgrade alone. Comes with new hardware too so win win!

Very well package looks really good. Shipping was fast really like them.

‎ Wow! I have been using Xotic Performance Parts for Several Years now with no issues whatsoever, I ordered the LS2 Rockers with the Pre-Installed Trunnions & Installed them in our 5.7L Engine. I am really impressed with the Quality & Construction of the Xotic Performance LS Rockers, Xotic Performance has updated their Trunnions to use C-Clip Retainers that no doubt will increase the service life of the Rocker Assemblies. I gave the Xotic Performance LS Rockers a Full Five Star Rating Across the Board

You need upgraded trunions if you want to run a cam with more lift than stock engines. It's a lot easier to install these rockers than convert old ones. These seem to be great quality hardware and work well. They are a fair value for a set of upgraded trunion rocker arms. I approve and would recommend. Same basically asMichigan.

The parts have not been installed yet but everything looks up to speed as far as upgrades are concerned.

I am rebuilding an LQ4, and had not planned on new rockers, but ran across this set and thought why not. I was only going to do a valve job and replace the springs and pushrods, but this is a very good quality upgrade. These are very well made and you can tell these are quality parts. These are very easy to install, since I already have the head off and was doing the valves and springs. This is a solid design that will function well on my LQ4. I think this is a very good value for the price and I am glad I found it before I finished the job.

This is an excellent set of rocker arms kit. Includes all bolts in a package. High quality and solid parts at a good price. No issues at all. Very nice indeed.

I installed the intercooler pipe as soon as it came in, fit was perfect and it was easy to install.

Swapping to the Xotic Performance LS1 rocker arms on my 5.3L engine was one of the best bolt-on upgrades I’ve done. The pre-installed trunion kit and quality hardware meant the install took less than an hour per head, and the arms slid right onto the studs without any clearance issues. Once torqued to spec, the valvetrain feels noticeably firmer—no more lifter tick at idle and valve lash stays rock-solid even at high RPM. I’ve put several hundred miles and a few spirited pulls on the dyno, and oil flow remains steady with zero noise or deflection. If you’re running a stock or mildly built LS2/LS6/LQ4/LQ9/LM7/etc., these rockers deliver reliable, precision performance without breaking the bank.
