U dowels for locating the rod cap. It allows the bolts to be positioned closer to the big end bore for improved big end stability. 3.18 DOWEL PIN The dowel pin is the alternative option to ring .125

BIG END POCKET The big end pocket relieves peak stresses at the 12 o’clock position of the big end bore and reduces weight.

C BIG END OIL SQUIRTERS This oil hole in the Big End neck allows pressure fed oil to squirt up to the piston and rod Pin End for additional cooling and improved lubrication. This option can be considered for engines without oil squirters. DOUBLE LOCKS To provide flexibility for a rod with different bearing configurations or for rods that require double bearings B

GROOVES IN THRUST FACE For weight reduction, grooves are machined on the big end thrust faces

33.02 R1.300 LIPPED CAP AND LIPPED CAP RELIEF When tension loads on connecting rods reach the higher limits of today’s automotive engines, we have seen an improvement in the big-end integrity by slightly increasing the contact area between the cap and the connecting rod itself. CP-Carrillo’s Lipped-Cap design achieves this goal .439 .430 8.13 .320
