ive been running a set of um o6s for 4 years now, with 40s, and 37s, and now 36s. and lets just say i do some nasty things to this truck. i have a high hp 22re, dual ultimate cases, dual lockers.

if it can stand up to my goofy butt for 4 years, its a product to stand by. are the longs stronger?? ya, but not by a whole lot. not cost effective. if your doing things that will break an un-o6, youll break a long shortly after
