How Much UnderDrive is TOO MUCH

[CheekyD1]

With several members now with extreme underdrives fitted I am looking for the answer to the question....
What is your total final drive ratio and how do you find it works?

Thanks

Hey Gary

Std low range in mine is 43.4:1
underdrive is 116.76:1

(269% lower)

I am running std 3.54 cw+p's

The biggest advantage of the Underdrive is that it doesnt mess up your existing gearing

At the Springs the other weekend the Underdrive was awesome.... I could idle everywhere including up the rock tracks behind the house.

At the wet levuka a few weeks earlier not so much!

You are more than welcome to have a go in it next time we catch up.

How much is TOO much??? Maybe when the snail on the ground is beating you

80:1 is good

120:1 is great

150:1 is gettin silly but still cool

anything over 180:1 is too much!

Love this bit

Pls note, although the Underdrive will fit the Disco LT230 transfer case it will foul the rear footwell so the bodywork will have to be modified to clear.

Pass the Sledge hammer please

I wonder how much 'adjustment' it needs?

Probably about a 10lb sledgehammer's worth.

I think Grimace summed it up pretty well.

If you go too low you can do as much damage because to the torque multiplying factor, I saw a brilliant youtube a while back of a jeep flipping over in slow motion because it just didnt stop - up up and over. it was going up and over a rock

No thats just a driver who has no idea what to do with all the toys he has on his truck
