When installing, follow the torque specs of 45 ft lbs for the 3/8' fasteners precisely. This will ensure a proper and secure fit. As for maintenance, regularly check the fasteners for tightness during routine engine inspections. Keep an eye on the overall condition of the rods. If you notice any signs of wear or damage, replace them immediately. Also, since they are made from high - quality materials, they can handle high - stress situations, but don't push the engine beyond its limits without proper support.
