These Carrillo Pro - H CARR connecting rods are designed for high - performance race engines. If you're installing them, make sure your engine is the VQ37HR, as these rods are only compatible with it. When tightening the 3/8th inch cap bolts, you can retorque them as many times as needed without having to replace them. Since these rods are made for 1000+ whp race machines, they're not suitable for regular street driving. For maintenance, regularly check the rods for any signs of wear or damage, especially after a race. If you notice any issues, consult a professional mechanic right away.
