I don't know how we went from talking about valves and cylinder heads to lowering leaves in under this topic, but I think I've mentioned before that I have never personally used lowering leaves because I do not believe in them and I know that I have read over the years many people have had many frustrations with them on these Mazda trucks they work on S10 trucks, but they have a horrible track record for working on Mazda trucks, so it's either airbags, hydraulics, or old school regular lowering blocks, angled of course, and take out a few leafs that are on the truck originally.
Belltech notoriously bad and do not fit our trucks.
