FS25 Low Range v1.0

DKK25 Low Range adds a working high/low transfer case to cars, pickups, Jeeps, and trucks in Farming Simulator 25.
Low range gives your 4×4 a 4:1 gear reduction, making it easier to crawl through mud, climb steep trails, cross rough terrain, and control your speed on technical off-road sections. It works especially well on logging maps, mountain maps, mud parks, and maps with tight trails where normal gearing feels too fast.
High range keeps the normal 1:1 ratio for everyday driving and road use. Switch into low range when you leave the pavement and need more control.
This mod is PC only. I have not tested it on Servers Yet.
Keybinds
The mod uses your existing FS25 group-shifting controls:
Numpad 7 — Low Range (L)
Numpad 9 — High Range (H)
These can be changed under:
Options → Controls → Vehicle → Shift Group Down / Shift Group Up
An H or L indicator appears near the speedometer so you can see which range is selected.

This mod only adds the transfer-case range. It does not automatically add four-wheel drive or differential locks, so it works best with vehicles that already have a proper 4×4 drivetrain.
This most works best with the Toggle Gear Shift Mod and the Extended Vehicle Mod found here. These 2 mods will allow you to have selectable 4×4, diff locks and transmission shift selection. I do not own these 2 mods.
