Does anyone know how similar the axles are between JKs and JLs (non-Rubicon)?

I see there are Truetracs that fit on the JK with the Dana 30 front axle w/ 27 splines. Has anyone tried to put these on their JL?

I previously emailed Eaton about the truetrac for JL. They had responded that they do not have anything that fits as of now. I asked about the future and response was “no plans publically”. I’m still holding out hope.

Thanks for sharing that. I’ve been browsing their website and was wondering the same thing. Does anyone know if it’s possible to regear with gears for the d30? I was thinking that it might be possible, given that both the ring and pinion need to be changed, and the new housings are slightly larger.

I did see some regearing options for the Dana 30 advanTEK (m186) and the dana 35 advanTEK (m200). Can’t find site right now, but noted they are out.

JK D30 and JL D30 use the same gears. They are not Advantek. Only the rear D35 is Advantek.

Dana Spicer offers 4.10, 4.56, 4.88, 5.13 for D30. Same part #s for JK and JL. The axles are different but the gears are the same.

So, a TrueTrac for 3.73 and up that is suitable for a JK should fit the JL Dana 30 then? Someone told me that they installed an ARB AD100 front locker on their JL Dana 30 even though it was stated it was for a JK Dana 30. Not that it wouldn't fit the JL, just a lack of data since the JLs are still "new". If that can fit then so can the TrueTrac. Is my line of thinking correct?
