Completely redesigned from the ground up, GForce S550 Mustang axles are unlike any entry-level axle on the market. Featuring custom built CV joints CNC-machined from proprietary aerospace billet, and the strongest 28-spline axle bar available, these axles are rated to 850HP+. As with all GForce axles, S550 Mustang axles feature single-piece inner and outer stubs, CNC-machined from billet steel and finished with black e-coat to protect against harsh conditions without impeding spline engagement, resulting in the strongest stub design available. In addition to their increased strength, GForce’s S550 Mustang axles feature the anti-wheel hop technology originally introduced by General Motors several years ago, offering significant reduction in wheel hop during hard launches. GForce S550 Mustang axles are a direct replacement for factory half-shafts, and are designed for cars with mild bolt-ons to those running superchargers and turbos. MSRP is $1299.00. Customers who may approach or eclipse these power numbers are encouraged to consider GForce’s Ford Performance Outlaw axles as a potential upgrade.
