Hey all
I searched and didn't see anything related to my question, which is what size u bolts apply to C3500?
Because there's a lot of confusion in parts houses between 3500HD and just 3500 (DRW / SRW etc) the fitment guide is not clear, but the following is what I think is out there, and that's kinda based on what I see Husky putting out there via RA, but also casual observation on a lot of roached out JY trucks.
C/K1500 (C=5x, K=6x) 9/16" thick
C/K2500 (6 bolt light duty) 9/16" thick
C/K3500 (8 bolt HD) 5/8" thick.
This is kinda what Husky is putting forward and I agree it makes sense although I will say looking at a lot of different trucks in the JY I can't say for certain that GM installed 5/8" bolts on the HD2500 trucks (or 3500), my evidence kinda says that's not true. In fact referencing my own C3500 it doesn't appear that the rear u-bolts are 5/8", they look to me like the 9/16" bolts on my K1500 that I just replaced TBH. Maybe there's another qualifier for the 5/8" bolts I'm not aware of? Like for only trucks with the 9200 GVWR?
If anyone has the skinny on bolt fitment I'd be interested in knowing how that all worked out.
I'm going to be replacing them sometime in the future, probably not this winter, and 9/16 or 5/8 it doesn't really matter but I would probably default to the larger just because.
This doesn't address length which I'm not going into here because that's not a problem really.
Any info or suggestions please post back...
Thanks
Steve
