The Lunati Pro Billet Connecting Rod is 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 re-balancing. The Lunati Pro Billet 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.  The exclusive "barrel" shaped beam and rounded end are designed to reduce stress risers and create a smooth flow that compliments the natural gain of the billet. Lunati 220,000 psi 7/16" rod bolts assure proper clamping load, and on the small end, burnished Ampco bronze bushings are honed to exact pin clearance. Rods are matched to +/- 1.0 grams. Closer tolerances and pride in workmanship, along with strict quality control make the Lunati Pro Billet the only logical choice for the serious racer.  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.

Pro Billet Rods are available in Standard, Super Light, and Super Duty configurations. The Standard series is designed for all race applications. Approximate weight is 670 grams. Pro Billet Super Lights are intended for 355 cubic inch flat top low compression applications requiring a lighter bobweight. Approximate weight is 615 grams. Pro Billet Super Duty rods are intended for 430 cubic inch dirt, Sprint car and other NASCAR type applications. Approximate weight is 650 grams. Pro Billet Big Block rods are intended for all types of race applications.

Lunati's Pro Mod connecting rod is stronger and lighter than most other steel connecting rods. Made from aircraft quality 4340 certified material, the Pro Mod connecting rod is the one that is most often chosen by leading engine builders, and it's approved by NHRA. Custom profiled on state-of-the-art CNC machining centers, the big end features an all new cam cut that greatly reduces the need to modify the connecting rod in long stroke applications. The I-beams are highly polished to help "roll" oil away from the rods. Quality 7/16 " Lunati 220,000 psi rod bolts are used in all rods. Connecting rod sets are weight matched to ± 1.5 grams per end. The small end is fitted with an Ampco 18 bronze bushing. Pro Mod Rods are available in Standard and Super Duty configurations. The Standard series is good for medium to high horsepower and torque applications for street, strip, road race and oval track applications. Each Small Block rod weighs approximately 625 grams. The Super Duty series is designed for a 400 cubic inch oval track type application. Approximate weight is 670 grams. ______________________________________ Tour Lite Rods MAN-14245 $1220 Forged from aircraft quality 4340 material Manufactured in Manley's own CNC machining centers Fully Machined to produce the very lightest and strongest rod possible Shot peened after machining to Mil specs and 100% individually magnafluxed Cap fastners are ARP 2000 or CARR 3/8 cap screws   530 grams 575 H.P. at 8500 RPM Feather Lite Rods MAN-14545 $1150 Manufactured from aircraft quality 4340 material Manufactured in Manley's own CNC machining centers Fully Machined to produce the lightest and strongest rod possible Shot peened after machining to Mil specs and 100% individually magnafluxed Cap fastners are ARP 2000 cap screws  483 grams 550 H.P. at 7500 RPM Pro Series Lightweight MAN-14455 $1130 Manufactured from aircraft quality 4340 material Manufactured in Manley's own CNC machining centers Fully Machined to produce the lightest and strongest rod possible Shot peened after machining to Mil specs and 100% individually magnafluxed Cap fastners are 7/16" ARP 2000 cap screws 612grams 750+ H.P. at 8500 RPM Sportmaster Rods MAN-14113 $620 Manufactured from aircraft quality 4340 material Manufactured in Manley's own CNC machining centers Entire beam and cap area is profiled to remove stress risers and render the lightest possible rod Shot peened after machining Cap fastners are 8740 alloy 3/8" (190,000 psi) ARP cap screw Premium Ampco pin bushings 595grams 550 H.P. at 8000 RPM ______________________________________ 2-ICR6125-7/16 $320 Forged High Tensile 4340 Chromoly Steel 7/16" ARP/Scat 8740 Cap Screw Lightweight "I" Beam construction X-rayed, Sonic tested & Magnafluxed Shot peened to stress relieve surfaces 600grams  750BHP 2-ICR6125- $280 Forged High Tensile 4340 Chromoly Steel 3/8" ARP/Scat 8740 Cap Screw Lightweight "I" Beam construction X-rayed, Sonic tested & Magnafluxed Shot peened to stress relieve surfaces 585grams  650BHP ______________________________________
