07-13 Mazdaspeed3 Connecting Rods

K1 Technologies Connecting Rods

K1 Technologies connecting rods are quality built from billet 4340 steel for superior strength in high horsepower applications. K1 has also called upon the experts at ARP fasteners to design special K1 proprietary rod bolts with asymmetrical threads to equally load each thread when under pressure. K1 rods are shot peened for improved fatigue life and are finished in the USA using only state of the art Sunnen hones. K1 rod housing bore tolerances of +/- .000050in (50 millionths) match some of the tightest accepted tolerances in the industry. All K1 rod sets are weight-matched to +/- 1 gram and boxed with the individual rotating, reciprocating, and total weights conveniently noted for balancing. A special wrist pin bushing material is also used with these assemblies offering optimal friction reduction.


  • Note:
  • K1 Rods are sold in full sets or four (4) rods.

Carillo Connecting Rods

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 inception 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.

Carrillos's Pro-Super A beam (Pro-SA) rods are lighter than the traditional H-beam style rod, yet still unbelievably strong. Pro-Super A beam rods bridge the gap between Pro-H and standard Pro-A rods, designed for use in mid to high horsepower and high boost turbocharged and supercharged applications. Pro-Super A beam rods allow for more horsepower and higher RPMs with the advantage of a reduced windage design. Pro-Super A beam rods for the 07-10 Mazdaspeed3 ship with standard 3/8th inch WMC cap bolts and are rated to 800whp, they are great for cars that see both street and race driving.

The H-beam rod has become the industry 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 are 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. These rods are for 1000+whp race only machines and are not optimal for street use.


  • Note:
  • Carillo rods are sold in sets of four.
