From Exotek Racing:
Lightweight Ti6 titanium rear axles for TLR 22 series buggies.
Machined with a tighter tolerance for less bearing slop than the stock axles and weighs about half the weight of the stock steel axles at 3.7gr each.
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 bones.
