Hi all
Just been reading all the posts about getting lower low range gears, and just think it might need clarifing, i know this might start a argument but this is what ive worked out.
The rule for going up hills is use second low, this is because first low is to torquey, and the torque exceeds the availiable traction, this equals wheel spin. Im positive about this because ive tried 1st low up a
hill(it was the first and last time :) So unless you have dramaticaly changed your tyre diameter have a lower low range will just be detrimental to your 4by.
Correct me if ime wrong cause im not getting gears because of this reason.
Regards Ben.

To me, there is no set rule, every
hill is different.
So are conditions, drivers, cars, tires, motors, weight, ground, etc are different. too many variables.
You should judge each
hill when you get to them, and then go from there.

Nope. you can put smaller tires on, its just for different terrains, some people like serious
rock crawling, so they need LOW LOW gearing.. Look at XRCC, Tuff Truck challanges. When your doing stuff like that you NEED LOW LOW!

Exactly right - depends on availble traction, torque approach speed etc.
I usually use 1st gear low for anything, then if that fails, 2nd gear and more moomentum and revs.
And yeah I consider a 15% radius increas to be a radical change........
I would like a lower LOW as lower approach speed = less potential damage......
Only rockhoppper
hill do for me - no possible diff gearing swaps :(

Ben - there are no hard and fast rules. Before I had a (front) difflock (GQ Patrol, with a good rear LSD), 2nd gear low was the go. Now, I walk up slowly, in low first if it is a steep
hill, particularly if it is rocky. Each
hill is different, and now I have superior traction.
Rock crawler gears simply mean that you can walk very slowly up a bumpy/rocky track. Tyres, engine, weight, rain, etc all make a difference.
Cheers
