    Just an fyi since I haven’t seen it posted anywhere even after searching here and on Google, the leaf spring center pin on our trucks is not a bolt like most, it has a 21mm round head, so even though belltech says their lowering blocks fit our trucks, they don’t. I had to buy a 21mm drill bit and drill the blocks to get them to fit, and the top pin was loose in the axle tube but that’s easy to line up as you tighten. I used 2’ blocks on mine because my tires stick out a bit, if you intend to tuck tire you will need 3”+.
    My pics are too big to post, but I assure you this is the size

    First pic is how they came compared to the truck pin, second is after drilling. I’m not sure about the depth, I just eyeballed it.

    I think it's great that we have to drill to our own spec.. cuz you can throw them on anything, hence universal! It's up to us to measure correctly and drill to fit. Good info.

    Was a bit of a hassle, but once I found a bit it was easy, and all the more frustrating since the Belltech website says they fit my truck….
