i think the only positive difference i have seen with the suretracks is that the axle doesn't vary in thickness like the oem axle does, and the boots are similar to the DSS boots.
however, metal chemistry is in question here. they say it meets OEM specs but, really?
they also use a double c-clip to hold the joint on the axle instead of 1 thicker clip, which i find odd.
this is the company that makes these, i believe.
When China can send us completely machined parts for the cost of what raw material is here in the states we do have to wonder how they do it, my guess ? China is a largest consumer of Scrap Metal from the US. So im guessing all those old Grand Prix's and Buick's are coming back in the form of CV joints. Most are not aware DSS was a large Cv axle and Rack and Pinion rebuilder from 1986 thru 2003 and when the parts from China started coming over they were real bad, tolerances and heat treat were terrible along with questionable materiel. They have corrected most of it but it does come down to material. There is no substitute
p.s. do you guys really want a "budget axle" a factory part will out last anything from China but we could make some inexpensive ones if you want to see them.
