PFF5-5301 includes a CNC-machined aluminum outer shell with a concentric bore for standard geometry alignment. With the machined shell, and reducing the amount of polyurethane material used, we have increased stiffness by a further 50% over PFF5-301 and PFF5-303, and a massive 250% over the standard OE rubber bushing. The results are incredible, with minimal deflection under steering load and braking, while maintaining a balance of compliance and performance.
