Overview
TKR5149A is a six-pack of aluminum differential cross pins from Tekno RC. Machined from aluminum rather than steel, they are the lighter option for racers chasing every bit of rotating mass out of the drivetrain.
The cross pin carries the spider gears inside the differential. These pins are supplied without gears and require the matching TKR5150 differential gear set.
