I actually just recently learned about these 6 lug 14 bolts and it's something I'm going to be on the lookout for. I'm definitely going to swap one in. I'll see how those drums work with the 4 piston calipers I just put on from the 2019+ trucks but right now I'm pretty occupied with getting my ls swap finished and driving so eventually it will get done.Does it have to be disc? I have an OBS 9.5 14bolt 6 lug with bigger drums (11"? Sorry can't remeber right now) and there was a very noticeable difference in stopping power right away. They almost felt too strong, until I put the 2500/3500 calipers in the front now it feels more balanced.
It's a direct swap, no weird or custom parts needed besides a conversion U joint. And you get a stronger axle out of it and the chance to choose a new gear ratio.
