Rocker arms

Does anyone know the rocker ratio of the commonrail? Also, what year trucks had the rockers without the stupid plastic cup on the tips and was the ratio for those the same as the commonrail? Thanks, Jay

1.34 TO 1 they are the same for both CR and 24 valve

Some of the earlier 24v's also have the plastic cups.

I don't think a 24V rocker will clear the CR injectors. The 99 24V I had had metal cups.

yes the 24v rockers will clear the cr injectors been running a set of 24v rockers in my truck for about a year and half now. pulled my head to check the pistons and found two rocker tips broken friend had a set of the 24v ones and they went in and never came out.
