If your truck has a limited slip differential (2 wheel burnout) you will need the 75-140 synthetic oil (just under 3qts) plus the friction modifier additive. If your truck has a regular differential (1 wheel spinner burnout) no shame. It takes the 80-90 gear oil also just under the 3qts. No additive needed. FYI the front differential takes the 75-90 oil just around 2qts
