SPL ND Miata Rear Upper Arms
SPL ND Miata Rear Upper Arms
The SPL ND Miata Rear Upper Arms (RUA) are designed to offer a significant range of rear camber adjustment for high-performance street and track applications, particularly for lowered cars. On lowered vehicles, the factory adjustment range provided by the OEM eccentric washer may not be sufficient to bring camber into spec, making these adjustable upper arms a must-have for precise alignment and performance tuning.
Key features include:
Gun-drilled 2024 Aluminum Center Links, Clamps, and Clevises, providing superior strength while reducing unsprung weight for better handling and responsiveness.
Blue Anodized Titanium Socket Head Cap Screws ensure durability and corrosion resistance in demanding conditions.
The 360-Degree Rotating Clamp System allows for easy adjustment with a 3/16" Allen key, eliminating the hassle of jam nuts and wrenches, and ensuring that your alignment settings are locked down securely.
FK Spherical Rod Ends replace the soft, worn-out bushings found in the stock rear suspension links, reducing unwanted alignment changes under hard cornering, acceleration, and braking. The Teflon liner inside the FK rod ends ensures smooth articulation, quiet operation, and eliminates bushing deflection under load.
The PTFE liner is chemically bonded to the race, offering a high load-carrying capacity, increased dynamic wear characteristics, and an operational temperature range from -65º to 325ºF, making these rear upper arms reliable for both street and track use.
These Rear Upper Arms are sold as a pair and are Made in the USA for high quality and durability.
