About the Rock Forged FF32

The Rock Forged FF32 is built using a flow-forming manufacturing process, a technique that applies high-pressure rollers to a cast aluminum barrel while spinning at speed. This process aligns the aluminum's grain structure, resulting in a wheel that achieves a favorable strength-to-weight ratio compared to traditional gravity casting — delivering meaningful performance benefits without the cost premium of full forging.

This Rock Forged FF32 is available in 20x8.5, +38mm offset, 5x4.5 bolt pattern. Finished in Black with a Machined Inner Lip.
