4/6 no doubt. If you go with a 2/4 you would most likely want to go lower like Y2kSierra said a 2/4 isnt that low in my eyes either. I can bet you would want lower.

As for as C-notching goes the fellas at fullsize.com have always suggest getting a c-notch on the NBS chevy's. For some reason the NBS chevy's tend to bottom out very easy even with a mild drop. Theres a lot of members over there with suspension experince. IM going with a DJM 4/6 on my truck.

 

Onthe VHO I would have to say go with the SS drop, a 2/3.

 

GO WITH A 4/6!! 2/4, you wont be happy. Hell, i have been tossing back and forth between getting a 4/6 or 5/7 drop for my truck. Get a 4/6 and dont look back. Notching the frame is not that big of a deal anyways. It just gives the suspension a little more room to travel. Good luck and i hope this helps!!

 

There is a mcgaughys GP goin on right now on one of the other GM sites.

 

4/6, I love mine.

 

seems like most people prefered the 2/4 back awhile ago, now it seems they prefer the 4/6

 

2/4 for a few reasons; one being that I would hate to drive around Austin on a 4/6. I was there last week for the first time with my 2/4 and it was rough around campus and downtown.

 

ya im i like the 4/6 but dont want to c notch the frame i think the 2/4 is looking good how much should i pay for the kit and in stall

 

VHOs have a torsion bar front suspension, so a 4" front drop isn't an option. I think the most you can get in the front is 2" using the SS kit kit like SCIV mentioned.

 

i noticed no difference in ride quality from 2/4 to 4/6
