* Suspension: Upgrades to the suspension were key. This likely included a higher ground clearance, potentially through different springs, shocks, and possibly a lift kit (though factory lift kits weren't always standard). Expect heavier-duty components designed for off-road use.
* Axles and Transfer Case: The 4x4 system itself would be a heavy-duty setup with low-range gearing in the transfer case for tackling challenging terrain. Axle ratios would likely be geared lower for better performance in off-road conditions.
* Tires: Off-road tires were frequently selected as part of the package. These tires would have a more aggressive tread pattern for better traction on loose surfaces.
* Protection: Things like skid plates (to protect the underside of the truck) might have been included or available as options.
* Other Potential Additions: Depending on the buyer's choices and the dealership's offerings, things like tow hooks, locking differentials, electronic stability control (ESC), or other off-road-oriented features could have been included.
In short, there wasn't a single "Off-Road Package" sticker on a 2005 Dodge Ram, but the term refers to trucks built with a collection of off-road-focused factory options chosen at the time of purchase. To know the exact specifications of a particular 2005 Dodge Ram 4x4 off-road truck, you'd need to see its build sheet or window sticker.
