The listing does not specifically indicate 3/8 diameter but the paper catalog does. They seem to have 3 different grades for a 454 3/8.
ARP-135-6001 $57.95
ARP-135-6402 $59.95
ARP-235-6402 $97.69
Your choice is to obvious one between the lower priced ones. The highest price ones are a different higher strength material than the ones under $60. Rods and rod bolts are the best place to invest in on a bottom end. If you are going to spin it up racing this is no area to cut corners on. $30 is nothing compared to the cost to repair the damage of a spun rod bearing. If the engine is going in a truck application your choice is fine. Perhaps someone else can comment as to the value of the best grade.

Ahmed,
Make certain that you are aware of the fact that the large end of the rod will have to be resized once you install those bolts. You cannot simply remove the factory bolts and install the ARP ones without machine work. ARP's web site has a lot of information about this.

sorry for this question
but what do you mean by resize the rod ? what type of machine work must be done ?
does it mean to bore/hone the big end then using oversized bearings ?

thanks
