BTR v2 trunnion kit
Who all are using these and what’s your opinion on them? Right now I have the stock rockers with the CHE kit in them and everytime I change my oil I have some fine glitter in there so I’m not sure if these are slowly wearing away or what, also there seems to be a little too much side-to-side movement. I was thinking about ordering a new set of BTR rockers with the version 2 trunnion kit already installed.

All the aftermarket trunions have their drawbacks. The GM rockers got a bad rap (deservedly so) from the early LS1 days when they would spit out the rollers. Not much of a problem with LS2 and LS3 rockers. Personally, I would buy a set of new GM rockers and throw them on, unless you have a huge cam and spin the motor really high. Then go aftermarket.

I have a stage 2 cam and don’t do any racing but I figured the BTR rockers are as good or better than the stock rockers. Prob similar in price also. Biggest thing is the trunnions are already installed

I agree 100% with farmington. I bought a set of bronze bushings and didn't like how they went together. Ended up buying new GM LS3 rockers and went that route. After 30K miles, I changed valve springs and got a new set of stock GM rockers. The old ones looked perfect, but with a .620 lift cam, I considered new springs and rockers to be maintenance items. I visit 7000 rpm quite often. The way I look at it, that's just a part of the cost of doing business at elevated rpm and power levels.

I installed the BTR V2 trunnions in my LS7 last Summer. I liked the apparent quality. I have read of some issues of the earlier BTR kit, but I haven't seen any issues yet on the V2. I haven't pulled any of the new trunnions to have a look yet, but I've only got 6,000 miles on them so far, so too early to really tell. The motor is still relatively quiet in the valvetrain, so no obvious problems.......yet.

like hell it shuts my motor up a bit to where the VT noise is tolerable. Actually my VT overall sounds good except for the drivers side, been chasing an isolated tick in the same spot since the day I bought it almost three years ago

Just a suggestion. Instead of going with the BTR trunnion kit, why not go with the BTR shaft mount system. Will have much better lateral stability and be much stiffer. It is a little more money but should be rock solid. And the bearings it uses are a roller style. I have never trusted the bronze bearings that all the trunnion kits use.

I am just sticking with the CHE bronze bushings. A bronze bushing in a well-oiled environment will hold up very well. AHP has done lots of testing on the CHE bushings with good results. I love the way they quiet the engine down. My valve train is stock, so I'm sure that helps too.

I think the bronze bushings probably quieten down the motor the best and for most ppl prob work very well. I’m not positive it’s from the bushings but my oil has some very fine dairy dust in it that’s not magnetic so I’m wondering if that’s the source. It’s in the heads too so I feel like that’s where it’s coming from. The BTR kit may or may not be as quiet as the CHE kit but I think I would feel more comfortable using those

We have used the CHE Rocker kit for 12+ years now and never had a single issue. Excellent upgrade over the stock needle bearings

I have dual valve springs so it sounds like a sewing machine. After I sorted out the push rod length everything is as it should be. No more chatter but the sewing machine noise is still there. The BTR V2 trunnions are solid. I never had issues with mine. I got a good deal on some Yella Terras and swapped them out. Now Im leaning towards the Comp Cams BSR system.
