what power will they take, i have ARP rod bolts also. just wondering if i need to go steel

 

Wouldnt go above 400 on them to be absolutely safe but they have been known to take more. I ran a set to 450 without issue but wouldnt advise this for anyone else unless they are prepared to take the risk and know the consequences of doing so.

 

400-420 area... as above have gone more but for how long...

 

do they bend above this or do the end caps break apart?

 

Mine have been replaced with forged ones for 400+bhp. I was advised so to do by one who knows
