Tekno RC has released a set of aluminum stub axles for their NB48.3, NT48.3, EB48.3 and ET48.3. These axles reduce the rotating mass by over 12 grams per pair. They are precision machined from 7075 aluminum and hard-anodized for strength.
They are machined with 3 cross-pin locations to extend the life of the parts.
These aluminum stub axles improve fuel mileage and suspension efficiency.
