Hello I just ordered a spartan front locker for dana 30. But been doing research that its saying it need an empty carrier or older style carrier. Anyone had problems installing spartan locker?

 

I thought you pull the spider gears out of the diff carrier and replace with the locker. Saw it done once (not sure of vehicle type) and it was done on vehicle. Isn't this what is referred to as the lunch box locker?

 

I thought so too. But people are saying jk carrier are made differently not sure why?? And yes its referred to as a lunchbox locker.

 

Do you have a link to your reference?

The only thing I can think of is some confusion about the carrier break between 3.21 and 3.73 for the front D30.

(This is in regards to regearing the axles, not adding traction --> a JK d30 with 3.21's uses a carrier for just that single ratio, so regearing to any higher numeric ratio requires a new carrier appropriate to the 3.73 or higher gears.)

 

I have a spartan in mine. Had to go to a new carrier running 5.13’s grizzly makes a carrier it’s only $80 I think

 

Just to clarify - Your new open carrier was needed because of the gear ratio change from 3.21 (to any numerically higher ratio), and not because you added a spartan, correct? Had you kept the stock 3.21 gears, the stock open carrier would have been fine. I think this is what the OP was getting confused about, but he hasn't updated his thread so it's just a guess...

 

that is correct the only reason I had to get a new carrier was due to the fact I went over 3.73 gears to a 5.13
