Z1 Motorsports Adjustable Front Upper Control Arms for Nissan 350Z and Infiniti G35.

We took on this challenge with a goal to produce the highest quality arms possible while maintaining competitive pricing and outstanding performance.

Inspected, assembled, re-inspected and packaged in house by Z1's trained staff, the front upper control arms arrive ready to install on your Z right out of the box. A professional alignment is strongly recommended after the installation of the arms.

Made of 4130 chrome-moly hardened alloy steel, these arms are strong enough to take any track abuse you can throw at them, while maintaining good ride quality and solid performance. They feature a durable powder coated black and silver veined finish which is attractive for show cars, and chemical resistant. all hardware is custom CNC machined with Black Hard Anodize and Bright Zinc finishes.

Control arms are 100% rebuildable and use sturdy heim joint ball joints for maximum durability and performance. Replacement ball joints are relatively inexpensive and available HERE.

Z1 Motorsports Adjustable Front Upper Control Arms feature an offset ball joint location in order to deliver an optimal caster increase. Increasing the amount of positive caster will increase steering effort and straight line tracking, as well as improve high speed stability and cornering effectiveness. Positive caster also increases camber when cornering as the steering angle is increased to keep your Z planted through hard corners. These control arm also offer an additional camber adjustment.

Our design allows arm length adjustment on both the inboard and outboard ends of the arm, providing the most range of camber adjustment for stance or tracking for the serious motoring enthusiast.  

Street versions feature Energy Suspension Urethane Comfort Bushings for minimum flex, and maximum ride comfort. They are fully rebuildable and will soon be available for purchase separately through Z1 Motorsports. They are also fully serviceable with included grease fittings for long product life and minimal noise.

Race versions feature heim joints with solid race bushings to minimize flex and maximize performance. As a result, increased vibrations and noise may be noted. Z1 recommends using our Street Version if this is a concern.

Due to their modular design, Z1 Motorsports Adjustable Front Upper Control Arms can be interchanged from Urethane to Solid Race components within an hour and can be purchased separately. This reduces the need to purchase multiple Upper Control Arms, greatly reducing expenses, leaving you with more money in your pocket!
