debating on my sr5 4x4 for trd offroad

Should I trade my 07 4x4 sr5 with LSD for a 4x4 trd offroad 2013 or just put a arb locker in the rear?

 

yes

 

Is your truck running fine? if so why replace it if it is not broken. Seems like an unneeded expense.

 

Depends what payments look like side by side with the new one. Gotta say though, I love the TRD's.

 

Does the new trd 4x4 offroad have LSD when the 2wd is engaged

 

no



Just drop in a ARB with on board air

 

Before I got my TRD OffRoad I owned a few different Jeeps going back decades. I had ARB's F&R in all of them. I love those diffs!!! If I was happy with everything else about the '07 I'd do an ARB (or two).

 

Will a arb locker fit in the rear with LSD rear or do I need to source a new ring and pinion?

 

As far as I know there is only one ring and pinion set for the taco rear, so it should be that the ASRB just replaces the LSD... same gears. The SRB application guide just lists one kit RD-129 for the Taco rear.
