PFA Aston Martin Suspension Lower Ball Joint Brass Bearing Cup
Precision steering begins with the smallest components. If you are looking to refresh your front suspension, the PFA Lower Ball Joint Brass Bearing Cup offers the perfect blend of heritage design and modern metallurgy. We have engineered these as exact, interchangeable replacements for original factory units, ensuring they fit seamlessly into your existing assembly.
Enhanced Material for Longevity
While our bearing cups maintain the exact dimensions of the original equipment (OE), we have significantly upgraded the construction material. Specifically, we utilize a high-grade alloy from Columbia Metals. To achieve a longer service life, we chose this specialized material for its superior machinability and wear resistance. As a result, these cups withstand the rigors of the road far better than standard brass alternatives, helping you maintain tight, responsive steering over time.
Vehicle Application & Installation
Beyond the material improvements, these units are highly versatile. In terms of compatibility, they suit a vast range of heritage models, from the early DB4 through to the AM V8 era.
Regarding your order, please note the following:
-
Sold Individually: These components are priced per unit.
-
Vehicle Requirements: Most restorations require two (2) units per vehicle for a complete lower ball joint overhaul.
