ARP Main Stud Kit for Miata MX-5 (1990-2005)

The ARP main stud kit for the 1990 to 2005 Mazda Miata replaces the factory main bolts and holds the main caps more securely, which reduces cap walk and fretting in a high power engine.

The kit includes the full set of ARP main studs, washers and nuts, plus ARP assembly lubricant. Professional installation is recommended, and follow ARP's torque and installation procedure.

On VVT and Mazdaspeed Miatas, the windage tray has to be modified to clear the length of the studs.

WARNING: Handling passenger or off-highway motor vehicle parts can expose you to chemicals such as phthalates and lead, which can cause cancer and reproductive harm. To minimize exposure, service the vehicle in a well-ventilated area, wear gloves, and wash your hands. For more information see www.P65Warnings.ca.gov/motor-vehicle-parts.
