If you are looking for connecting rods that can take whatever you can throw at them, look no further. Carrillo connecting rods are forged and use only the strongest materials to ensure they will hold massive amounts of power. They are run through a thorough inspection process once finished to ensure each rod is made to the highest quality standard. These rods are for enthusiasts that require the absolute best and will not compromise on quality.

The Pro H-beam rod has become the industy standard design for high-performance applications. Considering the best overall performance of the part, combined with the least amount of weight, the H-beam is Carrillo's strongest, most durable design available. Carrillo H-beam rods are recommended for race applications where no compromise in performance is possible. Pro-H rods for the Mini Cooper S available with 3/8th inch cap bolts in either standard WMC or Carrillo specific design which can be retorqued as many times as you want and will not need to be replaced.

Fits:

2002-2006 R53 MINI Cooper S Hatchback
2005-2008 R52 MINI Cooper S Convertible

Set of 4 rods.

Carrillo uses proprietary chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). The heat is validated, both by the supplier and an independent metallurgist whom confirm the desired physical and chemical properties of steel.

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.
