"... rocker arm retro-fit trunion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunion with a premium 8620 steel alloy trunion and caged roller bearings for added durability. The new design from COMP Cams® utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings, which can send loose needles throughout the engine upon failure."
While a lot of people would say this may not be a common failure (or at least not until you start getting into serious HP) a lot of people are doing the upgrade just for peace-of-mind. Also the people who have done the upgrade say it also quiets down the valve-train noise a decent amount. This instantly got me curious since I'd still like to quiet my engine down some more (exhaust is SUPER quiet ever since the mid-muffler install, now it's just the engine noises that are loud ).
I contacted Brian of Reckart Performance Tuning who seemed to be the go-to guy for this upgrade. What's really nice is that he doesn't just sell you the bare kit like most other vendors - he also offers to install the kit in either new or core-exchange rockers, so that you don't have to have any downtime (or you can even send your rockers in and he'll install the trunion upgrade for you and ship them back ASAP).
I recently received the rockers and I must say they look & feel super solid yet rotate very smoothly. I've heard people compare the stock rockers to feel/sounding like loose marbles in your hand when you shake them, but these things are solid!Now I just need to have them installed so I can give a full comparion to the 'before' vs 'after' sound.
So if you're interested in this upgrade, contact Brian over at Reckart Performance Tuning or find him on the GRRRR8 Forum as 'Brian@RPT'
