Ex Tax of 20% 


PEC's own in house design facilities are able to create many different components but for nearly 10 years now, it's our connecting rods that have helped set us apart from the competition in terms of availability, ease of fitment and size of range.

Manufactured from forgings originally produced in Sweden, PEC connecting rods have offered engine builders and tuners a cost efficient and yet high performing solution to a wide variety engine building problems.

H-Beam and I-Beam section connecting rods are forged from AISI 4340 (En24) steel. Heat treated to HRC 35-38 and then shot peened for a higher fatigue strength. Small ends are bushed for a fully floating pin and big ends are fitted with high quality ARP fasteners with different specification bolts available depending on the level of performance required. 

PEC Connecting rods have been designed, manufactured and tested to the highest levels of scrutiny before being released to the trade and the public alike and their success record speaks for itself.

Bolt specification

PEC rods are designed to withstand roughly 225hp per cylinder (typically 900hp on most 4cyl engines) and on the ARP 2000 series 3/8 bolts normally provided & have an 8,500 RPM safe operating limit (engine specific).

In some cases, we recommend using the ARP custom age bolts available from us. This increases the hp threshold to 250hp per cylinder and raises the RPM limit to 9,000 however as every engine is different, these numbers are not guaranteed for every configuration.

If in doubt, please contact us for advice.
