Well I was ready to tell ya about my 2/3 then you changed your mind.
I'll tell anyway and you decide. I orderd Summit's spindles and
3" blocks. When they arrived, I found out they where Ground Force.
The blocks were angled 2 degrees. You'll want to be sure you get
that so you can keep pinion angle correct. You may want to mark the
driveshaft where it goes into the trans with a grease pencil to see
how far into the trans it went. You don't want trouble there. This
is before and after you drop your truck. Some will say it's not ness.
3/4 play between the trans output shaft housing and the yoke is good.
If you have a x-cab you might want to ck the slip yoke that goes
to the carrier bearing. On the front guys here at this forum have
mentioned l/s lean after coil springs. I don't know about that, maybe
someone else will commet on that.
Anyway the parts from Summit/Ground Force went on real easy, eveything
fit good, and the rear blocks were made of iron not alum. So I feel
that the Summit pc's were decent as well as Belltech..The majority
use Belltech and like them a lot. I'm happy with the Ground Force
product. I cut the 3" blocks down to 2.5 because I didn't like the
rear being lower than the front..Now it's fine for me..
