I have a 1986 Toyota Extra Cab SR5 4x4. Years ago, I put plastic in the bed and filled it with water to make a small swimming pool. I am looking at my leaf springs now and they look pretty darn flat. I'm wondering if they are originally supposed to be flat? How much sweep should they have? Should I replace them? They just look too flat.
Welcome to the site. A good way to check vs others to see if you have extra sag is measure from the wheel lip to the center hub. That will negate tire size between trucks. Works to see how low people are too. Replacements are available online in stock height and lifted for your truck.
