Pec rods are designed to withstand almost 225hp per cylinder (typically 900hp on most 4cyl engine) and larp series 2000 3/8 bolts normally provided & have a 8500 limit of use of safe rev / min (special motor). In some cases, we recommend the help of the age personalized ARP bolts available from us. This increases the hp to 250hp threshold per cylinder and raises the rpm limit to 9,000 while each engine is different, these figures are not guaranteed for all configurations.
Prolonged high regimes for drift, or sudden torque bursts for drag race (for example), warrant the use of custom aging bolts to help maintain the clamping force between the end cap and the connecting rod. If in doubt, please contact us for advice. Beam and in beam i section rods are forged steel AISI 4340 (EN24). The heat treated hrc 35-38 and then blasted for greater resistance to fatigue.
Bits are banded dentrer a fully floating nip and large ends are fitted with different attachments with specifications of ARP bolts available depending on the level of performance demanded of high quality. Made from forged originally produced in Sweden, the pec rods offered tuners and engine manufacturers a cost effective and high performing solution to a wide variety of construction problems engine.
