Hello eveyone. I am a HD F-150 owner and i was wondering what # pulley comes on the L stock? Thinking about about going up to 4# and was wondering if that is the stock one for the L's. If it is, maybe someone has one that they'd like to sell.

 

The HD's come stock with 6psi......L's come with 8psi. So an aftermarket 6# lower will add 6psi for an L (total of 14, in theory) and 6psi (total of 12psi, in theory).

Hope this helps.
