Ultimate Avalanche - The Finale
|
Another issue that arose with The Carnage was that we actually twisted the splines on our 300M CTM axles. The best axle design is one where the shaft diameter is smaller than the root diameter of the splines as seen on the left. The old shaft on the right allows for the twisting in the splines since they are weaker than the shaft itself. When the shafts neck down after the splines, the twisting force actually works like a torsion bar, giving the shafts more spring to deal with shock load. CTM now makes all its shafts this way, and it keeps the twist away from the splines where it can start to cause breakage. View Related Article
