Spool Connecting Rods Feature:
-
CP-Carrillo uses a proprietary steel to manufacture its connecting rods, named Carrilloy. It is a chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). Carrilloy is simply a modification of an existing SAE specification. We just tighten up the acceptable attributes of the heat as it is manufactured. The heat is validated, both by the supplier and an independent metallurgist whom confirm the desired physical and chemical properties of steel.
CP Pistons standard features include:
- 5310 gudgeon pins (9310 thicker wall thickness pins are available as an upgrade)
- Deep valve reliefs accommodate high lift camshafts
- Larger valve reliefs for +1mm valve sizes
- Custom skirt cam and barrel design
- Accumulator grooves

- High performance rings
- Fully CNC machined and balanced to +/- 1 gram
- Wrist pins included
- Double pin oilers force fed from oil ring groove
- Pick lock grooves for easy lock removal
- Pin fitting included
Note: We recommend Joe Gibbs Break in Oil for all new engines.
