  • Pre-Assembled for Easy Installation: Each rocker arm comes pre-assembled with the bronze bushing trunnion kit installed, along with 16 new Allen head bolts. This ready-to-install setup saves time and effort, allowing you to upgrade your valvetrain efficiently and get back on the road or track faster.

  • Upgrade for high mileage LS1 with a cam
So far good for my LS1 with 220K miles on it. I had issues with needle bearings falling apart on my supposedly upgraded trunions. I found broken c-clips, cage pieces and needle bearings on my magnet oil drain plug for the second time in a few month so I decided to go with these. Install was easy, I soaked them in oil for a day and used assembly lub to be on the safe side since these bushings dont have the oil channels like others. What I've noticed so far is a quieter valve train and some more consistency in idle and through the entire power band. The rocker arms in this package are NOT OEM rockers so only time will tell if those hold up or have a problem. The cam I'm using is .600 lift and duration isnt anything crazy but it's hopefully good peace of mind moving forward. One tip, if you have needle bearing issues and opt to do this it would be a good idea to run a magnets over the top of the cylinder head as I found more needles hidden in some of valley's of the heads, glad I didnt miss that. ... show more
