F8X Axle Upgrade

Included: A complete pair of axles with billet inner and outer stubs.
 
Upgrade your M build with the strongest axles on the market. Designed to match the robust capabilities of the M drivetrain, these heavy-duty axles ensure maximum performance and reliability.
 
The axles feature a 31-spline 300M axle bar and billet-machined CV joints. The additional splines provide greater engagement, allowing for larger-diameter axle bars that offer unmatched strength.
The billet-machined CV joints not only improve spline engagement but also deliver greater travel and a wider operating angle compared to OEM CV joints. These enhanced CVs offer superior anti-wear characteristics, significantly increasing durability over standard options.
 
To further elevate performance, the axles are equipped with anti-wheel hop technology, originally pioneered by GM. This technology dramatically reduces wheel hop during hard launches, ensuring smoother and more consistent power delivery.
 
Proudly hand-built in the USA, these axles are meticulously crafted using only premium materials. Each assembly undergoes rigorous quality control to ensure long-lasting performance. In fact, we still run the original prototypes on our own cars—proof of their reliability!

Outlaw Upgrade: For those seeking even more power, our Outlaw upgrade is the perfect choice. Featuring enhanced CV components, this option retains the 108mm design but uses upgraded billet-machined internals and an isotropic surface finish for a mirror-like polish. This surface finishing ensures smoother CV joint operation, reducing heat, minimizing wear, and aiding grease migration. The Outlaw axles also include premium ARP fasteners, delivering the strongest CV axle bolts in the industry.
