The Ultimate High performance connecting rods at last for the Focus RS Mk2

Brand new by K1 and ready to go the newest edition for the highest-powered focus RS Mk2 2009

These are some of the highest quality rods on the market.
They are only for fitment with standard pistons or wiseco pistons
They are fitted as standard with ‘ARP’ rod bolts, recognized as the best available.
These new Focus RS Connecting Rods are manufactured from a TWO-PIECE FORGING. The forging process forces the grain into the shape of a connecting rod, resulting in a superior fatigue life. The rod cap is forged separately so that the grain runs perpendicular to the load forces, which strengthens the connecting rod. Many aftermarket connecting rods are manufactured from 4340 steel. 4340 specs allow a range of different materials to achieve the desired results. Although it is a more expensive process, these contain a higher content of nickel & chrome, which increases the strength & fatigue life without making the connecting rod brittle.

Proper rod bolt torque is vital to connecting rod life. A rod bolt fastener is without question the highest stressed fastener in the engine.
Insisted on the best ‘ARP’ from PUMASPEED.
