Trunnion Kit Options:
These rockers come with your choice of BTR trunnion kit pre-installed:

BTR Upgraded LS3 Rocker Arms
These things feel and look much nicer than the OE. Not having to worry about the OE bearings failing with a high lift camshaft is definitely a plus.

Btr rocker arms
I bought these btr rocker arms with the tk02 trunion kit installed to finish off my build. The pads on the rocker arm is a huge improvement over stock and has more wipe area for higher lift cams like the one i installed. The valve train is also very quiet with this setup. I would highly recommend these. Shipping was very fast and secured!
