Set for Porsche 986/987/996 2.5/2.7/3.2/3.4 with WMC bolts ( the long rod )
CP-Carrillo connecting rods are fully machined from a proprietary 4330m alloy forging for strength and durability.
Rods are available with 2 types of bolts:
The standard WMC-H7 (H11) bolt with a UTS of 220ksi
Upgraded CARR-S7 (MP35N) bolt with a UTS of 285ksi
The CARR upgraded bolt is a good choice if planning on revving the engine higher than 8500rpm.
All our bolts are manufactured with asymmetrical threads, each thread has a slightly different design than the previous giving the bolts an evenly distributed thread engagement. This helps to increase the clamp load and fatigue life of the fastener.
