I just installed the TMC rear lowering kit and this thing is awesome. My rear end was sitting a little higher than my front and it was bothering the h&ll out of me. This kit dropped the rear about an inch and now the car sits totally level.

I was actually going to install the 5 leaf mid eye...saved myself a ton of money.

What does the 'kit' consist of? Lowering blocks, shackles?

Gotta be lowering blocks with new ubolts. The factory shackles are just too short to be shortened further.

Out of curiosity, is there a reason NOT to use lowering blocks?

So long as you keep them to around an inch or less, I can't see any problems. If one were to get carried away and use a 3" block, there could be some issues.....

Biggest reason is that lowering blocks increase wheel hop problems. They also tend to be prone to cracking/failure, but I think that's because of crappy design/materials more than anything.

I've seen a lot of posts where guys have said they're going to replace their perfectly good leaf springs with 5 leaf mid eye's in an effort to stiffen the ride and lower the car and inch. I guess to make the car sit more level. I was just wondering why more people didn't just use the lower blocks.

And yes, I'm using the new longer uBolts.

Machined aluminum would work also.
