The factory rod bolts are the weakest part of the factory rods in the M113K engine. Weistec's ARP M113K Rod Bolts are much stronger than the factory bolts and are a must when assembling an engine with OEM Rods.
With 220,000+PSI of tensile strength, our ARP 2000 rod bolts are able to keep the connecting rods together with far greater pressure than the factory bolts, allowing you to safely make more power, and have increase rev limits via Weistec ECU and TCU Tuning.
