Notice how im in 02-08 model trucks. Along with a driver side axle change you also have to change the ring and pinion for this to compatible. According to Moe's Performance this is the strongest available option for the newer 4th gen trucks... but you will have to pay for it.
Moe's Performance:
"The Trutrac is the strongest LSD available, but it is a more complicated swap for the 9.25ZF. You would also need to purchase an older 9.25 ring/pinion and a 2nd driver side axle shaft to use on the passenger side. That is what I run in my own trucks. Its more than double the cost of the Mopar LSD, but it is the strongest option we have.
If you just have a daily driver that you need both tires turning, the Mopar LSD is more than enough though. I race my trucks, so I wanted something stronger than the OEM.
