CARRILLO CONNECTING ROD SET (4) PRO SUPER A-BEAM (SA) – LOTUS/TOYOTA 2ZZ-GE (CRL-SCR4254-4)

Description

Carrillo’s Pro Super A-beam rods have a tapered design for increased strength compared with Carrillo’s conventional (cheaper) standard A-beam rods. Includes high grade tool steel H-11 rod bolts. Suitable for naturally aspirated and forced induction applications.

note: all 2ZZ aftermarket rods have a wider than stock small end for maximum durability; this works fine with all 2ZZ aftermarket pistons. OEM pistons are quite narrow in this area and must be machined slightly for clearance (most people do not install aftermarket rods with OEM pistons).

All heat treat processes are via a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 while maintaining the critical elements of low notch-sensitivity and ductility.

All Carrillo connecting rods are manufactured from an oversized forging resulting in the proper grainflow as well as the surface removal of any potential inclusions or surface conversions generated by the forging process. All critical CNC machines at Carrillo are equipped with probing to accurately validate dimensional integrity. In the production process each part is magnafluxed at least twice, further each piece is Rockwell tested to validate the heat treat procedure. A final shotpeen operation completes the part.
