I got rid of the spacer and replaced it with Eibach Springs. Didn't like the spacer, too soft, the springs are much better!!
This maybe a dumb question. You used the Eibach Springs in front. What about rear? Rear TSB? What is meant by TSB?
It's the Technical Service Bulletin that Toyota put on Tacomas. It was an extra leaf spring that gives it more lift and weight capacity.
