My new extenders came already on Sat(thats was fast I just ordered them thurs night) well anyways. they are well stout in design,and these are MACHINED not casted either...I also like the way they use and o-ring inside outer nut ... these are worth the money IMO... I also added my little .75 caps to the ends of them to keeps dirt out of them
I'am been using these caps on the front axles on the 5bs since the 5b came out...
Here you can see the end cap
here is just a pic of the little caps I use
