Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth. Connecting rods connect your engine's pistons to the crankshaft. Replacing your connecting rods doesn't necessarily add horsepower, however they are essential for maintaining horsepower. If you are looking to boost your car and make high numbers of power, we strongly recommend replacing your OEM connecting rods with a stronger aftermarket setup. CP-Carrillo has one goal in mind: offer high quality performance products with excellent customer service. We strive to provide the best internal engine components to the customer; offering both pistons and rods is a tremendous added value for our customers. These two pinnacle products are crafted at our headquarters and manufacturing plant in Irvine, California, USA where cutting edge technology and traditional craftsmanship skills come together. We believe quality is the fundamental and overarching principle that drives us to excellence. Carrillo SCR5357-4 CA Residents: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
