awesome, thanks for the help guys i guess gearing is the way to go.
gearing wont affect the car while in 2H will it ? and will it still have enough go in 4H to smash the mud ruts ?
In a 1.3 Sierra transfer, there will be a small reduction in high range. This will complement your 30" tyres and give you a lot more 'go' on-road.
Smashing mud ruts is probably best done in low range - unless you like hitting your mud at 50km/h+.
