they put the end caps on the rods and tighten them then they hone the inside where the bearing sits it stops new bearings from spining when you get it running

Yeah shot peening aint really worth it unless your gonna be revving high and making huge power, i wouldnt bother with the ARP bolts either unless once again your planning on running a fair bit of power 250rwkw +

shot peening relieves stresses in the metal by givving a modeled surface as stated above good for motors with more power.

If you want to prepare standard rods for more power, you want to get the sides of the rods beam polished to relieve any stress points, get them shot peened ( blasted with tiny steel balls to harden the surface) and then closed and honed which makes sure they are back in the correct shape and size for the bearings. Total cost might be up around $300?

when i got my engine built the builder said shot peening is not really necossary as std rods are strong enough for a fair bit of power. we just used a set of arp rod bolts and got the rods all freshened up/balanced etc...
