G-FORCE PERFORMANCE GTO LEVEL 2 28 SPLINE, 1-PIECE BILLET INNER AXLE STUBS

GForce Engineering GTO Level 2 Billet Axle Stubs are a direct replacement for factory stub-shafts, and are designed for cars with mild bolt-ons to those running superchargers and turbos.  Our level-2 GTO 1-piece CNC machined inner stubs are machined from a single piece of billet steel.  GForce inner 1-piece stubs are the strongest possible stub we could fit in a 28 spline design.

• The GForce GTO Level 2 inner stubs use an exotic steel that helps give a considerable increase in strength over the factory inner stubs. This is the first component of the axle that will see torque input, so it is generally the most abused component of the axle.
• Ultimately, the factory rear end will be the limiting component for making more power reliably, so if you are considering making well beyond 650hp, you might consider looking into the GForce 9” conversion (contact us) which has helped customers make well into the 800-1000 range, with a handful of cars up around 1500hp. Important to note that any axle can fail at a lower power level due to wheel hop or misuse. The listed numbers should not be an expectation, but an idea for capability.
