Cosworth Performance Racing Connecting Rods

The connecting rod is the vital link between the piston and power. When engine output is increased, the demands placed on the connecting rod increase as well. To ensure engine reliability in all conditions, original connecting rods should be replaced with heavy duty specification parts. Cosworth Forged Connecting Rods are manufactured from high strength 4340 (EN24) steel and machined to exacting tolerances.

Cosworth Racing Performance Rods Feature:

• Strong, light weight H-beam design
• Heavy duty rod bolt (260,000psi)
• Manufactured from 4340 (EN24) steel
• Small end bushed for floating pin

Cosworth Performance Racing Engine Bearings

Engine bearings are one of the most vital components within an engine and are often overlooked when considering high performance upgrades. Performance engineered, multi-layer Cosworth bearings generate less heat than normal bearings by reducing friction. Cosworth Race bearing sets feature a unique combination of design, metallurgy and engineering to deliver performance in extreme conditions. Cosworth Race bearings sets are available in two sizes to accommodate most applications. Size “1” bearings are a nominal standard size and are used for most applications. Size “2” bearings feature an additional .001” clearance and should be used when extra clearance is required.

Cosworth Performance Engine Bearings feature:

• High strength overlay plate with reduced thickness for better oil control and less friction
• Hardened steel backing on all connecting rod bearings
• Increased crush for better retention
• 3/4 grooving on Main Bearings providing optimum oil supply
• Tight consistent wall tolerances
• Oversize chamfers where applicable
• Flash plating eliminated for improved heat transfer
• Tested to over 1000 horsepower!
