Those axles aren't hard enough to have needle bearings rolling on them. Like the Long's birfs, it appears that they sacrificed surface hardness to gain some strength. I'd go back to OE unless they can prove that they have it fixed. If you'd like to measure the hardness on a Brinell gauge, let me know.
