Shockwave axles are made from seamless cold drawn steel for better wall thickness consistency and axial flex characteristics, and finished using the finest centerless grinding techniques. There is no straighter axle anywhere. Our 50mm axles also have an added feature: we weld a sleeve under the inner keyway for the drive gear to prevent shifterkarts from twisting the axle apart under acceleration.

Shockwave 50mm axles are available in three grades: Hard (2.3mm wall thickness), Medium (2.0mm wall), and Soft (1.75mm wall). Axles are engraved the first letter of the grade for easy organization. All 50mm axles are 1040mm long.

They all use pegged keys with two pegs for the hubs and pegged keys with three pegs for the drive gear or sprocket carrier and brake disc. Therefore, you will need two Pegged Key (size D2) and two Pegged Key (size D3) for each 50mm axle.
