Sorry, I thought the XB4 and XB2 used the same front wheels. I just looked it up and confirmed that the 2wd uses a different part number for the front wheels. I was also wrong on the name, as it looks like the XB2 is actually called the XB4 2wd
This sale includes 5 pairs of
4wd front wheels/tires and 5 pairs of rear wheels/tires (will fit both the 2wd and 4wd XB4's).
Price dropped to $90 shipped. The inserts alone are worth about that, and as most know the AKA inserts can be reused multiple times and usually get better after being reused once or twice.
