As I noted in the post above, the center of the pigtails on the Moog CC805 springs are a bit larger than the stock springs. After running them for a bit, I decided I wanted to center the spring better.
Today I used hockey pucks (2 per side) to enlarge the diameter of the bump stop post to keep the springs centered.
The bumpstop extensions included with my 2.25" BB from 4wheel customs
The new increased diameter bumpstop posts.
These next 2 show how the puck helps center the spring much better.
First, I drilled a 1 3/4 hole through the center of the pucks. (A tight fit over the extensions).
Next, I used a sawzall with a wood blade to taper the top of the top puck to fit over the spring isolator.
After reinstalling the springs with the pucks over the bumpstop extension, you can see how the spring is held centered in the spring cup.
I know how the usefulness of hockey pucks on Jeep applications has been highly contested on this forum. I do not see any reason why these will not work flawlessly for the life of the Jeep though in this application. There is no compressing force on the pucks that could cause them to deform. They are only seeing minute lateral pressure when the suspension is at full flex to keep the spring centered.
