Hey, Boi Pac1218 gets the win this time. You can show off your coolness with them without having to open your valve covers at the local car show. They also come with stickers that you can use to show off your coolness.
The upgraded rocker arm will fit the 8 series. As soon as I replaced the stock valve springs on my 2011 Corvette Grand Sport (LS3), I installed the Pac Racing valve springs. A set of 1 rocker arms with a set of Comp Cams 1 is included. You will receive one Ultra Pro Magnum rocker. In the time since the installation, I have logged about 1000 miles and the engine continues to perform well up It was recommended that I purchase these springs based on experiences with others running this combination, and they seem to be a good fit.
The product is great.
These springs are great and easy to install.
They fit great on the stock LQ4 As far as we can tell, there are no problems with this tune.
You should know how to install it. An easy way to install.
It came with a chevy 4 when I owned it. With a stock cam, they ran up to 7800 RPMS, no float whatsoever.
I installed them on my cam only 5 times. Not yet ran version 3, but have installed it. The same ones are on another cam, but there are only five. I have 3 of them and they are all great.
