Looking for some info on the NV241 J vs. NV241OR

 

[crusty1007]

The NV241J from a JK doesnt have a speedo option. It also comes in 2.72 or 4.0/1 low

NV241OR 03-06 Rubicons has a speedo and comes in 4.0/1 low.

241C in a chevy has a slightly different bolt pattern is a 2.72/1 low
(Early models were right drop)

241D same 2.72/1 low & has the chrysler bolt pattern like the Jeeps.
(some came as right drop) (after 98 possible no speedo option)

EDIT:
You can't use the JK 241 in a TJ/YJ series that needs a speedo. UNLESS you give the guys @ ORO a call and use their speedometer retrofit that gives you an external speedo on the JK (They use it for their Airock setups)

JK vs. TJ

Is there a difference between the NV241OR in the JK vs the TJ. I would like to buy one but I don't want to buy the wrong one.
