okay i was search around and i found a set of arp rod bolts part # 208-6401 for a decent price. i have a LS. these rod bolts say 9mm. will they work on the LS rods? i've seen only two part numbers for B series rod bolts: 208-6401 (9mm) and 208-6001 (8mm)

which one do i use for my LS rod?

 

Your name is Boosted k20. When you state that you have a LS that your needin' some rod bolts for? If you boosted your K20 then picking out rod bolts should be a walk in the park. You need the PN 508-6001. which are for 1.2-1.8L. VTEC models are different.

 

yep, if not you have to machine the rods to fit the bigger bolt

 

boosted k20 is just my sn. i gots an LS.

i was just curious cuz i seen a set of arp rod bolts sell n and the guy told me that they are for all B series motors. so i just asked that question to make sure. those rod bolts wont work for my LS. i need to get the 8mm one's. and im gonna take it to a machine shop to press in as well

 

Just don't forget to check the rod big-ends for concentricity. They should be no more than .0005" out of round with the new rod bolts pressed in and stretched to spec.

If they are, then an align hone is in order. Talk to your local performance racing machine shop about such a procedure.
