    Part No. KASTX15>9M4449S
    Or
    Part No. KASTX15>9M4449H ,,,which i guess is the H-Rod.

    other than the increased durability of these connecting rods for a motor build is there any notable benifit over the OEM rods. My motor is out at Kawasaki for GIO under warranty and they have been very good to me so far. I can put in other parts as desired (at my cost) while the motor is out. I think all they are going to do is piston/rings (leak down approx 25%). I am probably going with different aftermarket pistons, may have to pay for this but worth it while the motor is out. Any suggestions?

    Ask them to put 09 pistons in ,,,The conrods are expensive but good if you do more mods later,,as they are very strong and light weight.( Corrillo Rods )

    under racing condition H-11 bolts (KASTX15>9M4449H) need to bee replaced from time to time

    SPS-CARR (KASTX15>9M4449S) designed to be a non-replacement bolt.


    so KASTX15>9M4449S is the way to go!
