Why do you guys think there should be a bushing? The procomp mount doesnt use one. All the load should be support by the spring, so any force in that direction will compress the spring, so you dont need a little bushing there to absorb load. Obviously having bumpstops is important to prevent shock loading. You can still use the included bushing on top of the spring pocket for when you jack the truck up.
As the suspension cycles up and down the angle of the shock, in relation to the top shock mount, changes slightly - this happens regardless of whether a stud-top or an eyelet is used. The bushings on the top and bottom of the stud allow the shock to pivot as the the shock angle changes slightly. The procomp mount doesn't need a bushing because the shock's eyelet allows the same pivoting that the bushing normally would.
The way each of you configures your ride is up to you, but when using a stud-top mount I'm always going to have a bushing on the top and bottom of the stud. I don't know of any OEM or aftermarket setup that omits either bushing with a stud mount.
That's pretty beefy...I dig it! I was going to make these for your upper mounts, but to be honest, I'm glad you're tackling this because you know the dimension of your own parts best.
What bushing material and size are you going to use for the top and bottom of the stud mount with those washers?
