Why are there so many ifs and buts floating around about the eagle rods still? Forget all the crap you have heard from people. The long and short is all new 7m Eagle rods come with 3/8's arp bolts which are way stronger than the toyota bolts. Same size bolts in the 2jz Eagle rods. NOTHING wrong with the bolts!!! The rods are plenty strong. As with any rod, just check the toerances as Doward has already said.
