Boostline Connecting Rods Won’t Bend Under Big Boost

Perfectly good connecting rods will bend under the incredible cylinder pressure loads of turbocharged and supercharged engines or engines running large hits of nitrous oxide. BoostLine Connecting Rods are designed to survive under big boost. The 4340 steel rods have a hybrid design that combines the strength of an I-beam rod with the light weight of an H-beam rod. They also have triangulated pockets where the big end meets the beam area. This arrangement drastically increases the rod’s resistance to bending by 60% and reduces in-tension stress by 20% compared to a typical H-beam design. That makes them ideal for engines with a combination of forced induction and high cylinder pressures.

Boostline rods are individually measured using a Zeiss automated coordinate measuring machine (CMM) that logs a literal blueprint of each individual rod. After a production run of rods is measured, they are individually screened and combined into custom-matched sets based on overall length, big- and small-end diameter, rotating and reciprocating mass, and total mass. For a typical set of BoostLine 6.125 inch rods for an LS engine, center-to-center length variation is less than 0.0002 inch while total mass variation is just one gram.

Other features include:
• Heat-treated, shot-peened, and fitted with ARP-2000 cap screws before final finish machining
• High-quality Ampco bushing material used in the small end
• Pin clearance between .0009- and .0011-inch allows engine builders to spec custom wrist pins for additional clearance
• Detailed inspection report with critical measurements included to save installation time
• Each rod vacuum-wrapped for corrosion protection

BoostLine connecting rods are rated up to 1,000 horsepower for four-cylinder engines, 1,500 horsepower for six-cylinder engines, and 2,000 horsepower for V8 engines.
