cut and sleeve rubicon arms

ok i have adjustable upper and lower rubicon arms and drop brackets i am going to ditch the drop brackets for long arms instead of making all new arms i am considering cutting the lowers and sleeving inside some 2'' dom and use the upper for a radius style arms has anyone done this i think the rubicon arms are chromoly and thin walled from post i have seen before but it should work right

I don't see how it wouldn't work. Go for it!

Just retube the whole arm. I don't really seem much use in sleeving them when it's not a whole lot more work to clean up the joints and use them with whatever material you want.
