Default LS2 Rod replacment

Putting new rods into an LS2 motor due to a spun bearing. The crank will need to be machined... What aftermarket rods anyone recommend? this is just going to be a mild 224 cam build. I would like something as strong or stronger than stock and has a good price point.

Callies compstar, or maybe K1 or Eagle depending on your budget. All those can be had for under $600 (under $500 for the Eagles) and are all stronger than stock and will be more than ok for the mild build you're doing.

SCAT I beams are probably the best bang for the buck. They're less than $350.

A stock con rod with an ARP bolt upgrade will work plenty fine for now. An aftermarket H-beam style rods are getting cheaper and would be a good long term investment as well. But not to many people will go that route without putting a better piston/ring package on at the same time to.

new ARP bolts are for sure as well as new piston rings. if i change rods do i need new pistons? or as long as i use stock length rods can i reuse my stock pistons?

Before ordering just rods, make sure the piston pin size is correct. Most aftermarket rods will have a different size from stock.

Callies Compstar p/n CSC6100DS6A2AH

stock length 6.100 (basically), stock pin size
I used these on a stock crank LS2 and very happy. $436 if you call Callies direct, these are listed as 'overstock' so the price is good
