A stretched or rusty upper-arm bolt lets the Z32 front end wander after an alignment. The Genuine Nissan Front Upper Control Arm to Mounting Bracket Bolt is the factory upper-link bolt that pins the front upper control arm to its mounting bracket.
This is the long upper bolt on the member-and-link side of the front suspension. Two are required per car. It fits Fairlady Z and 300ZX Z32 models, USDM 1990–1996 and the matching JDM cars, NA or twin-turbo. Diagram lookup is 54550A. Approximate size is M11.5 × 136 mm. Use a new nut with each bolt when the joint comes apart.
Replace both sides when arms, bushings, or brackets come off. Hardware-store bolts do not match the length or shoulder the factory joint needs. At Terra Firma Automotive, we supply this genuine Nissan Z32 front upper control arm bolt so Fairlady and 300ZX owners can lock the arm to the bracket with the correct OEM fastener. Choose Terra Firma Automotive for authentic Nissan suspension hardware built for the Z32.
