ive read about ppls underdrive pulleys not fitting right when you switch to a double roller what my question is will my slp underdrive pully fit on the ls2 chain i got on the way?

 

You better move this back to the Newbie Section. It doesn't even make sense?

 

i have the slp underdrive & ls2 chain and all is ok !

ls2 isnt double roller

 

yes it will work

 

ok thank you

 

I think what you're talking about is double rollers requiring that people shim the oil pump. In any case, changing only chain and keeping the same sprockets like you're going to do doesn't have any impact on the pulley, pump, or timing cover. You don't have to worry about it at all.
