What is the main benefit of using monoball bushings over stock rubber bushings?

Monoball bushings replace the flexible rubber with a low-friction spherical bearing. This eliminates bushing flex and bind, which helps maintain consistent suspension geometry under load. The result is improved handling precision and better feedback from the road.

What vehicles are compatible with these rear upper arm monoball bushings?

These bushings are designed to fit a range of Nissan and Infiniti vehicles. This includes the Nissan 350Z (2003-2009), 370Z (2009-2020), and the new Nissan Z (2023-2024), as well as the Infiniti G35 (2003-2008), G37 (2009-2013), and Q40 (2015).

Are any special tools or procedures required for installation?

Installation of monoball bushings typically involves pressing out the old rubber bushings and pressing in the new spherical bearings. Due to the nature of suspension work and the need for precise alignment, it is recommended to consult the manufacturer's installation instructions and consider professional installation or alignment after fitting.

Product Details

If you're looking to get more out of your suspension, these Rear Upper Arm Monoball Bushings from SPL Parts are a solid option. They replace the stock rubber bushings in the rear upper control arms with low-friction spherical bearings. This change gets rid of the flex and bind that rubber can allow, helping to keep your suspension geometry consistent, especially when you're pushing the car hard. You'll notice improved handling and better feedback from the road.

SPL Parts uses FK racing bearings, which have a self-lubricating Teflon liner for durability and smooth operation. The bearing shells are precisely machined from T6061 aluminum to ensure an accurate fit. These bushings are designed for a range of vehicles, including the Nissan 350Z, 370Z, Infiniti G35, and G37. They are made in the USA and machined to very tight tolerances, down to a thousandth of an inch, for a precise installation and optimal performance.

This kit includes everything needed to replace the bushings on one car. By eliminating the compliance of rubber, these monoball bushings help maintain proper suspension alignment under load, which is crucial for predictable handling and a more connected feel to the road.
