Insane Shafts High Performance Axles for BMW 3 Series M3

Each application includes both left and right side axles (2 total).

As power is increased, weak points may begin to appear. Stock axles are great for stock or slightly modified engines, but will break once a lot of stress is put on them. Insane Shafts manufacturers high performance axles with strength and reliability in mind. Each axle is rated (at the wheels) for 500 HP to 1000 HP and directly installs on your BMW 3 Series M3! Each axle is made of chromoly steel put through Insane Shaft's proprietary annealing and heat treating process. It is then cryogenically treated to provide even more strength for high horsepower builds! In addition to all this, Insane Shafts puts all of their axles through a rigorous testing process to ensure they can handle the heavy demands even on dedicated track BMW 3 Series M3s. These axles are a great way to prevent you getting stuck on the track or on the side of the road with a busted axle simply because your engine is making too much power for your stock axles.
