you can run any AE spring just use the bottom shock collar for the tc5 so you can get the correct ride height.

Perfect advice! I also trimmed the lower shoulder so the pieces met at the top and bottom of the spring retainer instead of just at the bottom. It helped gives me all extra space I needed.
