What is the main benefit of installing a main cap girdle?

A main cap girdle ties the main bearing caps together, creating a much stronger and more rigid foundation for your crankshaft. This significantly reduces the risk of main cap flex or walk, especially in high-performance or high-RPM applications.

What material is the Moroso main cap girdle made from?

This main cap girdle is constructed from solid steel. This material choice ensures it can withstand the considerable forces encountered in performance engine builds.

What should I check before installing this main cap girdle?

Before installing, ensure your engine block and main caps are thoroughly cleaned. It's also a good practice to verify your main bearing clearances to ensure proper fit and function.

Product Details

This is the Moroso main cap girdle for Ford 289 and 302 engines. It's a well-built component designed to add significant strength to the bottom end of your engine. If you're building a performance engine or pushing your stock 289 or 302 harder than usual, this girdle is a smart addition to prevent main cap walk and potential crankshaft damage.

The girdle works by tying the main bearing caps together, creating a much more rigid structure for the crankshaft to spin within. This is especially important under high RPMs or heavy loads where the forces on the crankshaft are immense. Moroso uses solid steel construction for this part, ensuring it can handle the stresses of performance applications. It's a popular choice for engine builders looking to add that extra layer of durability to their Ford small blocks.

When installing this, you'll need to ensure your block is clean and that the main caps are properly aligned. It's a good idea to check your main bearing clearances before installation. This part is designed to fit directly onto the Ford 289 and 302 engine blocks.
