i have read alot about dynatrac axles. i would love to have a pair. they are VERY stout hevy duty axles. they are much stronger then a standerd d60 axle. they are more for compitition rock cralling in my openion though, mainly because of there price. kinda that unabtanium thing where there priced for the thick wallet people. there is alot of machine work in one of there axles, and held to tighter tollerences then your production axles cause there custom made to order axles. i personly feel they are the best on the market, but do most need axles like that. obviusly not. a good old d60 built with some upgrades is more then enough for probably 99 % of the wheelers out there. i will never buy a dynatrac axle simply for the fact that i am too poor to ever afford one.
