ARP Main Stud Kit for 1990-2005 Mazda Miata (218-5401)
$122.77
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1990-2005 Mazda Miata models including Base, Mazdaspeed, LS, SE, and special editions.
The ARP Main Stud Kit (218-5401) is a critical upgrade for any Mazda B-series engine build, providing the consistent clamping force necessary to secure the crankshaft main caps. Unlike factory main bolts that twist during installation, these studs remain stationary while the nut is torqued, resulting in more accurate loading and protecting the threads in your engine block from excessive wear.
Whether you are performing a stock rebuild or preparing a high-boost turbocharged application, these studs offer superior fatigue strength and reliability over OE hardware. Each kit is precision-engineered to handle the increased internal pressures of high-RPM operation.
- Manufactured by ARP for exact tolerances and maximum strength
- Provides more consistent clamping force than factory main bolts
- Simplifies engine assembly and protects block threads
- Includes all necessary studs, parallel-ground washers, and nuts
- Manufacturer Part Number: 218-5401
