Im lifting my 05 QC 4x4 by doing a level kit, add a leaf, and body lift. The aal comes with shock relocator brackets. Will I be able to get away with just OEM length shocks without them topping out? Also is there a major difference between a bilstein 5100 and like a pro comp 9000 or rancho 5000 shock? Is it worth the extra 150 dollars for them. Im going with heavy *** 37'' tires so I want the max support.

 

i am pretty sure the stock shocks will work with 2 inches.
but its never a bad idea to change out the shocks.
i had bilstien 5100's on my old 2000 chevy silverado and loved them

 

yes get new shocks, a level lift will pretty much fully extend them, getting a set thats a little longer will greatly increase your ride as well as help you get the most out of your leveling kit

 

you need new ones. when those shocks top out (and they will...even over speed bumps) its pretty rough. ive seen people crack windsheilds because they hit a pot hole and the shock topped out so hard it cracked the windshield...

 

You won't need longer shocks if you install the relocation brackets, that's what they are for - keeping your stock shocks.

BUT I would omit the relocation bracket and purchase a GOOD shock because of the tire size you are going to. Bilsteins or Rancho 9000s or Pro Comp MX6s. I wouldn't even consider the ES9000s or even the Rancho 5000s for that size tire...

 

Yes get new ones. I got the procomp ES9000`s and I love them.

 

But if I go with the rancho 9000's or bilsteins wont I still have to use the relocator brackets since they only come in oem length?

 

When I ordered my procomp ES9000`s I just called up 4 wheel parts and told them that I needed some that was 2 inches longer than stock for the front and then stock size for the back.

 

But wouldnt it be best to install the relocator bracket and just order the shocks at OEM length. Im not arguing Im just trying to do whats best for my situation.

 

I can't vouch for the Bilsteins, but I own Rancho 9000s that are made for 4" of lift in the front and 2.5" of lift in the rear. Dunno why you think Ranchos are only made for OEM height?

As a rule, the longer the shock, the larger the components are, which is why I recommended not using the relocation brackets and going with a longer (larger) shock. But it's up to you, stock size shocks and the relocation brackets will work also...
