MMR ARP Block Main Cap Side Bolts for Ford Coyote & Voodoo (2011–2024)
The MMR ARP Block Main Cap Side Bolts are a proven bottom-end upgrade for 2011–2024 Ford 5.0L Coyote and 5.2L Voodoo engines, designed to increase block rigidity, improve bearing life, and enhance overall engine durability. By reinforcing the main caps, these high-strength ARP side bolts help prevent cap walk and block distortion—critical factors in high-RPM, boosted, and race-driven applications.
Manufactured to MMR’s exacting standards and using premium ARP hardware, this kit provides superior clamping force compared to factory bolts. The added support stabilizes the main caps under extreme cylinder pressure, promoting more consistent bearing wear and improved crankshaft stability. One of the biggest advantages of this upgrade is that it can be installed with the engine still in the vehicle, making it an excellent option for preventative reinforcement without a full engine teardown.
Compatible with all Ford 5.0L and 5.2L engine blocks, including Boss and Ford Racing blocks, these ARP block side bolts are a must-have for serious street builds, track cars, and high-horsepower race engines alike.
