Connecting Rod Assembly - Big Bolt Rod Set

Unique Diesel's Big Bolt Rod Set. This is a custom set of connecting rods that have been modified to upgrade from the smaller 10mm fastener these engines come with from factory. This will fit 6.2 and 6.5 engines.

These start out as brand new connecting rods that we remove the factory bolts/studs from and install our custom stud and modify the rod to accept. This process require the rod bearing end of the rod to be re-sized to square up the assembly. We take a minimal amount off but this does alter the overall length of the assembly by .002" - .003" shorter. This is to save the expensive process of removing the wrist pin bushing, new bushing and boring and honing to set the factory center to center length again.

All forms of this rod undergo precision length and weight modification, and are only sold as a set.
