Brian Crower Toyota A90/Supra B58 ARP 203-5409 Main Stud Kit

This kit includes the main studs you need to secure the crankshaft in your Toyota B58 engine. These are from ARP, a well-known name in fasteners, and are designed to handle the increased stress that can come with a modified engine.

The studs are made from a strong, heat-treated alloy steel that ARP uses for many of their performance applications. This material offers improved tensile strength over stock bolts, which is important for keeping the main bearing caps properly seated under higher loads. ARP's rolled threads are also more resistant to fatigue than cut threads, helping to ensure reliability. When installing, remember to use the ARP assembly lube provided with the kit on the threads and under the nuts to ensure accurate torque readings and prevent galling.

This kit is not CARB approved and cannot be shipped to California.
