Regear: 4.3 >>> 4.9
Ever since swapping tires to 33”, monty became little sluggish and suffered a little on uphill.
Finally got to time to swap out the diff this past weekend. So far I just replaced the rear one to try out and have been driving in 2wd mode.
Stock setup was 4.3 : 1 ratio with LSD
Replacement is 4.9 : 1 ratio with open diff.
Ride is so much better. From the stop, it is not faster or anything. 1st gear acceleration just got shorter. But so much of improvement on uphill and highway acceleration.
Where 2nd gear would be under high load, 1st gear would be revving engine pretty high. Now it can cruise uphill in very relaxed way with 2nd or 3rd gear.
Now I have couple questions:
if possible, I would like to swap my factory LSD into this new housing.
Is it worth doing the work to swap LSD ?
How well does factory LSD work when in need ? Is it better just going with Air locker like ARB?
Anyone with experience? Appreciate your input.
