No. They are 5x4.75. But after a bunch of research I found that there is a bearing assy. from a Dodge Ram that will bolt into the NBS spindle. It has a 5x5.5 bolt pattern. This gives it enough meat to re-drill for our 5x5 pattern. You have to use a custom rotor anyway to get anything bigger than, I believe, 14". So it doesnt change anything price wise.
gotcha. I'm starting with the 6-lug option because I think it will be the easiest to make it work, and a lot of guys will go 6-lug just for more wheel options. I'm trying to figure out a way to be able to use off-the shelf parts so that in the long-term, the brakes won't be cost-prohibitive to run. I'm thinking cut the ears off the GMT-400 spindle like the S-10/F-body guys do, drill/tap for GMT-800 caliper, cut down a 6-lug rotor and turn it into a hub, use a GMT-800 rotor to match the caliper. it's all theoretical and none of it may work, but I'm going to try it. I think there's a significant market out there for 2wd brake upgrades, and if nothing else, it will help out guys that are willing to get greasy and DIY it.
From what I understand:
For OBS 4x4
- upgrading to 00-05 master cylinder only will upgrade brake pedal feel and performance
-upgrading to 00-05 master cylinder AND OBS 1 ton calipers will NOT improve performance but return back to same pedal feel. This is because the new 1 ton calipers offset gains in fluid from NBS master cylinder. This will only improve performance if you have or instal hydroboost, which uses a higher psi to push bigger bores.
-upgrading to NBS master cylinder and NBS knuckles, rotors, calipers, pads is the BEST way to get true improved performance. It requires reaming though.
sounds about right. I have the GMT-800 Master, GMT-800 dual-piston rear brakes, and GMT-400 1/2-ton fronts. definitely a better pedal feel, and much better stopping. still need to get a tapered reamer and the rest of the newer model hardware to do the fronts, but I have one side already. it will probably be a spring project.
ccredell - the purpose of the dodge hub is to re-drill for the chevy pattern, but how do you use the GMT-800 spindle on the 2wd front end? I was thinking machine a little "window" in the spindle, and install the ball joint 180* from stock.... essentially making it like the 4x4 setup. the "window" should give the LCA plenty of room during a turn. not sure how possible that is, but that's my thought. am I nuts?
