Quick Question. Currently gathering parts for a G5x2 install. I have the cam, i am currently looking for valve springs. I got my eye's on A set of 921's. are these springs A drop in deal? Thanks Larry

 

If you need $$$ their are many other options, if $$$ is a no issue then they are what you are looking for. And yes they install like all of the other springs

 

SEARCH BUTTON.

As with all duals I am aware of you will need the "kit" that includes new retainers and seats. It is essentially a drop in deal and 921's are a good spring. You could use 918's as well.

 

definately make sure if you get dual springs that you get the seats and seals to match....i was in a hurry and didn't by everything in a kit and it cost me about 2 days on my cam install.....if not for that i would have had it running in a day.
