2004-2007 Cadillac CTS-V Connecting Rods

The Lunati Pro Billet Series Connecting Rod used by professional race engine builders all over the country. Exacting tolerance and precision weight matching make this rod an easy replacement for competitor's billet rods without extensive rebalancing (a typical 6.00" small block Chevy rod weighs 670 grams). Plus, the Lunati Pro Billet Rod is stronger and more durable than comparable billet steel rods on the market. The quality of the 4340E billet is undisputed, and serious racers know that demanding conditions require the very best parts available.

Lunati's Pro Billet Rod is computer designed and CNC profiled to be stronger, lighter, and more durable than all other billet rods being offered. The exclusive "barrel" shaped beam and rounded end are designed to reduce stress risers and create a smooth flow that compliments the natural grain of the billet. The big end was configured with the cam cut necessary for longer rod lengths and the increased stroke utilized in so many race engines today.

Designed and Produced with Engineering and Finishing advancements, CompStar connecting rods have what it takes to make your engine build trouble free and your finished product reliable. Produced from heat treated and stress relieved 4340 material, CompStar rods are fully machined with a shot blasted Stress Riser free surface. Every detail of this highly stressed component has been carefully analyzed to maximize repeatability and dependability. See for yourself why CompStar can improve your bottom line and reputation.

· PARTING SURFACE EDGE CHAMFERED
This is normally done by the engine builder to prevent scraping material from the backside of the bearing insert during installation of the bearing into the rod.

· BEARING TAB SLOT FREE OF BURRS
Many competitor's rods share a common issue of burrs left in the bearing tab slot during manufacturing. In this situation, the burr prohibits the bearing locator tab from fitting into the receiver slot in the rod.

· PIN BUSHING CHAMFERED BEFORE HONING
Another common problem is a burr on one, or both ends of the wristpin bushing. This occurs when the manufacturer trims, or chamfers the bushing after honing to finished size. In this case, the pin either won't slide into the bushing, will slide into one side, but won't pass through the other, or fits tightly in the bushing, as if it has insufficient clearance.

· ARP 2000 SERIES BOLTS
The ARP 2000 bolt is an upgrade from the typical 8740 material used in most rods of this type. Use of this bolt increases clamping force between the rod and cap by approximately 2000 psi.

· RE-TORQUE DURING MANUFACTURING
During manufacture, CompStar rods are initially torqued and rough honed. The bolts are removed, and the rod & cap are then separated allowing the release of residual stress. The rods are then reassembled and re-torqued for final honing. This assures that the rod will still be round when you install it in an engine.

· LESS PREP TIME
By incorporating the above features into CompStar rods, the end user is saved a minimum of an hour of his valuable time. Few things can be more annoying than to unpackage a product for use, only to find that it's not really ready for use. Callies' goal is to produce a rod that's ready for assembly right out of the box.

· SUPERIOR QUALITY CONTROL
Finish honing is done on a state of the art Sunnen Krossgrinder. Tolerance is less than .0002" maximum out of round, taper, hourglass, or barrel shape. The bearing housing surface finish typically has an RA of 9-13.
