Description

BoostLine connecting rods are designed specifically for demanding turbocharged, supercharged, and big nitrous applications. The patented, 3-pocket body forged from premium 4340 steel incorporates the best features of both the H-beam (mass/weight) and I-beam (strength) designs. This provides 60 percent more bending strength compared to common H-beam rods. Each piece is heat-treated, shot-peened, and fitted with ARP-2000 cap screws (strong, malleable, and 220,000 psi rating) before final finish machining. Keep things straight with a set of BoostLine connecting rods (also available individually). Order the connecting rods in the model recommended for your specific engine size.

Features, items, and specs:

* High-quality Ampco bushing material used in the small end
* Pin clearance at between 9-ten-thousandths and 11-thousandths of an inch (allows engine builder to custom set wrist pin spec, should additional clearance be necessary)
* All BoostLine rods are individually inspected via a coordinate measuring machine (CMM) that is used to custom-match sets of rods to incredibly tight tolerances
* Each rod includes an inspection report from the Wiseco Piston quality team
* Rods are completely separated by thick foam for protection from shipping damage
* Each rod is vacuum-wrapped in plastic for corrosion protection
* Upgraded ARP 625+ bolts (260,000 to 280,000 psi) available
