From Exotek Racing:
Lightweight Ti6 titanium rear axles for the stock B6 and B5 series buggies.
Best suited for stock classes for reduced rotational mass and weight needed in the hot 17.5 classes (not suggested for modified use).
Works with the stock or MIP 65mm bones.
Only 7gr for the pair.
Note: use part #1786 for the new 67mm bones and off set hubs.
