Fitment Notes

• Sold individually (one ball joint per package); the arm uses two ball joints, so order accordingly if replacing both
• Confirm this ball joint is the correct match for your specific Cusco arm part number before ordering, as Cusco service ball joints are not interchangeable across different control arm applications

Product Description

The Cusco 251 474 K BJ is a service replacement ball joint made specifically for the Cusco 251 474 K front adjustable upper arm, used on the Z33 350Z and CPV35 Infiniti G35. Rather than replacing the entire upper arm once the ball joint wears out, this part lets you swap just the joint itself - a more targeted and cost-effective repair for owners already running the Cusco arm.

It's sold individually, so if both sides need attention you'll want to order two. Since Cusco's service ball joints are matched to specific control arm part numbers and aren't interchangeable between different arms, it's worth double-checking that this is the correct joint for the arm currently installed on your car before ordering.
