From Exotek Racing:
Titanium lightweight yet heavy duty replacement bones for the 22 3.0 MIP Bi-Metal Bone Puck sets with ball diff.
Half the weight of steel (each bone weighs 2.9gr) and twice the strength of aluminum so that you achieve a lightweight drive line but increase the durability and reduced wear and tear.
Made of polished and laser etched Ti 6-4 titanium.
Be sure to use a small amount of blue thread lock for hardware and black grease at pivot points when assembling.
1 pair of bones per pack.
MIP Bi-Metal Bone Puck axle sets with MIP ball diff required and not included.
