Is 3" too much lowering on blocks?

Hey guys,

I am having my lowering blocks made at my buddies fab shop, I am having him make a 2" kit out of thick wall 2"x2" square tubing. And then 1/2" add on blocks out of 1/2" flat bar.

So my question, is going 3" on blocks going to cause any issues you know of? Or will anything need to be changed? I have seen some guys do it with bagged trucks but mine is all stock height right now. Cause man does this truck sit all stink bugged out (raked) right now, I don't think that 2" is going to do much or get me level.

Thanks guys.

Re: Is 3" too much lowering on blocks?

Ah, I totally forgot about that. I am hoping to go with 18" or bigger so I should be good with a flat, but hope it doesn't rub on stuff when normal driving like different heights in the road or something.

Re: Is 3" too much lowering on blocks?

The scrub line thing is important to me, and I see it come up when we talk drop using blocks. But when bagged trucks that drag frame or obviously are below scrub line no one says a thing, just how cool it is. I find that amusing LOL.

Re: Is 3" too much lowering on blocks?

I started off with about 3" blocks and not only did it seem to affect my pinion angle but it also gave the rear end a feeling like it was "walking" on me. It's kind of like with a leaf rear end.....when you pull the axle away from the spring, you are giving it more leverage to axle wrap. This is what make a car wheel hop real bad under super hard acceleration.

I wound up going from a 4" drop to a 6" drop rear spring and then just did a very small block with a pinion angle shim and it made a big difference in the feeling under power. My motor has a ton of torque too, being a 460 BBC. That might have magnified things. I'd get as much, if not all out of a lowering spring and go from there.

P.S. I just realized that I don't know if you have a coil or a leaf rear end. Bottom line is the same issue applies to both. If you drive like a grandma or have no power.......probably won't be a big deal then.

Myself, I don't think I would go over 2" with blocks. Just one of my personal quirks...

Re: Is 3" too much lowering on blocks?

Thanks guys, I am going to see what 2.5" looks like and go from there. Another question is at what point am I going to have to worry about the panhard/trac bar? at what drop do you need to get an adjustable bar?

Re: Is 3" too much lowering on blocks?

bagged trucks can also add a little air to raise them back up ... blocks, not so much.

That's a great analogy!

When it comes to the panhard bar, the adjustable one is just too cheap not to have. Do you even know if you rear end is centered in the first place? It's a great tool and worth the little $$$.
