Additional Notes
- The Dodge Ram SRT-10 8.3 V10 rear differential carries a limited slip unit across all three model years covered, and the specified fluid capacity is 147 CM3 of LS-additive fluid in every case.
- A capacity of 147 CM3 is a relatively small volume, consistent with a limited slip additive top-up or friction modifier dose rather than a full differential fluid fill, meaning the figure represents the additive portion added alongside the base gear oil.
- The LS-additive designation applies uniformly across 2004-2006, indicating the rear differential requires a friction modifier supplement to maintain proper clutch-pack behavior inside the limited slip mechanism.
- Under severe use conditions, a fluid change interval of 15,000 miles is specified for all three model years, 2004-2006, with the same 147 CM3 LS-additive capacity retained at each change.
- No change interval appears in the normal use rows for any of the 2004-2006 model years, while the severe use rows consistently carry the 15,000-mile change figure alongside the capacity value.
- The capacity figure of 147 CM3 and the 15,000-mile severe-use interval remain identical across 2004, 2005, and 2006, indicating no revision to the rear differential fluid specification occurred during the production span covered.
