I'm kinda enjoying the altitude!!

It's interesting that the belltech catalog does not list the 3" (6403) shackle for the 07's NNBS, yet the 2" (6400) is listed. If you look further back, the NBS trucks use the 6400 and 6403 in same apps so they must be interchangable. I wonder if there is a clearance issue there with the 3" or just an oversight?

One thing I keep asking and never get an answer for (maybe I'm just stupid?): Stock clearance on the front (for my truck anyway) is 5" top of tire to wheelhouse. The wheelhouses on these things basically go straight in horizontally from the fender lip so if you drop it 5" you just lost all your suspension travel. you guys must have good roads... Rear is 8.5" with another 2" up into the wheelhouse so lots of room there...

Also, how much can you drop before needing drop shocks in the rear?

 

How did you get the 20" wheels on the SLE1 interior... I was told you can only get the Z60 package w/20's on SLE2 and SLT?

 

It appears you can't order the 20's on a reg cab in the States (so I've been told by several people now), but you can up here in Canada. Go to gmcanada.com and build one. I have no idea why it would be different up here. It does include the Z60 suspension as well, which seems to sit a tad lower than the ones I saw with the 17's (or maybe an illuision with the 20's).

 

i ordered both the 6400 and 6403, if the 6403 doesn't work i'll use the 6400 and return the other. i'd like to end up with 2/3 drop

 

I just noticed my truck seems to have a spacer block between the spring and the axle mounting plate. It measures almost 1.5"! I can see why it would be necessary except for the extra lift. If it could be removed it might be an easy way to get a small drop in the rear. My truck does have the Z60 suspension also, ECSB.

 

Yeah DJM has a 3" rear drop and they use the 2" shackle plus remove the block (my truck has it too). Haven't had a chance to roll around under the truck and look real close but I know their kit removes that block and then has some other plate plus new bolts so the block may be helping to align things?

Looking forward to seeing if the 6403 will work...

 

Was looking to see if anyone had word on this yet or not. I sent belltech an email, but got no word from them at all.
