Hi Phill and Neal,
Sadly, the Black Durango rears are out of stock at present (the ONLY DE Borrego buggy wheel we are out of at present) but they are on our current order with DE which will be on its way to us shortly.
We do have in stock plenty of both the fronts, Black 4wd (Durango DEX410 and will fit Xray XB4 also) and the 2wd fronts for the DEX210 also.
We also have all of the others colours in stock at present too in 2wd front, 4wd front and rears (yellow, white or silver) plus if it is any use we also have in stock the DE Black wheel sticker discs, so you can run a coloured wheel with the black discs if you wish for another alternative look...
The full range from DE racing is kept and listed by several of dealers, see the full list on our website -
