Originally posted by 2GeclipseRS I've heard helical lsds are the shit. I've also heard friction disk diffs are more responsive and more aggressive but wear out faster and need to be maintained alot more often. By wear out, i mean if those disks get to hot, you're fucked and then it feels like you have no diff at all. I guess it all depends how abusive you are and what the application is. Alot of people use disk-type lsds without problems. I've heard bad things about the obx diff. Fuck, i've heard bad things about obx in general. I dont think i'll buy any of their products. They can't control their quality worth a shit and are just pumping out parts making that money. That's not comforting.
