Our own H-Beam connecting rods to replace the original Triumph GT6, TR250 and TR6 connecting rod.  Produced from ultra-pure double vacuum remelted aircraft grade 4340AQ steel, heat treated, cryo treated and shot peened.  These are the absolute finest connecting rods you can purchase.  They come standard with 5/16" diameter ARP brand bolts (Carillo uses a 1/4" diameter bolt), rod bolts are available in two tensile strengths providing cost savings for customers who have lower RPM requirements. 

• Radial H-Beam, stronger and lighter than conventional straight H-Beam
• Less overall mass and greater torsional rigidity than X beam rods
• Interior pocket wrist pin oil holes which do not compromise small end strength, like rods that have the wrist pin lubrication hole at the exterior top of the rod
• Balanced across the set to +/- 1 gram
• 465g overall mass

We strongly recommend using a rod bolt stretch gauge when installing your rods to determine the correct pre-load on the rod bolts (utilzing a torque wrench is much less accurate). 

Priced individually, but sold only in full engine sets, make sure to buy the appropriate quantity (either 4 or 6)!
