Duratec 2.5 Forged Connecting Rods

The connecting rod is one of the most highly stressed components within the engine and improved connecting rods are an essential upgrade for high power Duratec engines.

The mountune Racing connecting rod was developed using FEA analysis resulting in the optimum connecting rod for high cylinder pressure applications. Made in the UK, each connecting rod features a robust, ‘H’-beam configuration that optimises weight without reducing strength. All edges have corner radii to improve durability.

As an added upgrade, mountune Racing connecting rods feature machined tangs to securely locate the rod bearings. Compared to the factory press fit tangless bearings, this feature ensures improved bearing retention in high cylinder pressure and high RPM engines.

Tool steel connecting rod bolts are also standard and are superior to most bolts found in other rods on the market.

Beryllium small end bushings provide a durable and low friction surface that remains dimensionally stable in high pressure and high RPM applications.
