I was thinking about making a spacer for my driver's side 5100 to counter the Taco lean.
My idea was to turn (on a lathe) a piece of round stock into a 1/4" long sleeve that would slide over the strut body and sit on the C-ring that the lower coil stop rests on. Basically, the sleeve would have the same outside diameter as the outer edge of the C-ring.
I'm no mechanical engineer, so is there any reason why this would be a bad idea or would be prone to failure for any unforseen reason?
On another note, if you ask me, I think that 5100's should have twice as many C-ring grooves as they do, all at roughly 1/2" intervals so that you can mix and match the height settings asymmetrically on either side of the truck to counteract the lean if so desired. In other words, rather than just have .85", 1.75", and 2.5", they should have .85", 1.3", 1.75", 2.125", and 2.5" or whatever
