63% reductions suit GQ & GU patrol [QLD]

[Rock Trol]

The price is good as well. I paid $1500 for my gears direct from Marks.

If someone buys my 35's AND RIMS FOR 15hunge I will buy them. Lol

Cheers blokes, will check out their graphs tomorrow for sure! The OP’s 63% advertised isn’t a standard gear though it seems and custom made it appears. Very interested us as it’s looking like the perfect happy medium for our family trucking needs :-)

Yeah Love Ke70 started by doing a group buy on these ratios across both Patrol forums and has since been buying them by the pallet as Marks will only do them as a custom ratio with a minimum order. I'd expect him to have more than one set. He almost should be chatting to @AB about a vendors thread.

From all accounts it's a great ratio.

Great idea there for sure mate!
Heard a rumour that installing the 85% gears requires some slight case rib cutting which would worry me a little bit. Sounds like his 63% fit in no sweat which would be ideal too!

You need to grind the case for the 63.

Thanks JaySee mate, is it much off or just a whisker off an edge?

There is also slight grinding required for 43% gears as well. Only the 24% gears fit straight in.

Don't know, I got them installed. Didn't like the idea of moving around a transfer case that weighs more than me.

From what I read and remember I think a die grinder was used.

Wow, I did not expect to get so many responses on here!!
I had a run of 50 and only have a few left now

Starting from the top..

Thanks Cuppa, they are a great piece of kit

Mark, to answer your question, each ratio change is about 5%
so 3.9 to 4.11 is 5%, 4.11 to 4.375 is 5%, 4.3 to 4.6 is about 5% too, so that is about 15% reduction.
These gears are a 63% reduction, but obviously only affect your low range.
For a reference, compared to your standard low range gears you have now, low 3rd is a gear between your current first and second low range.
Low fifth will be just a bit slower than your current high second

Mudski, wanna pay a set off over a few weeks?

Jaysee, very true, the downhill control is what I wanted and I love them I dont know how I went without now I have had them for so long I love it!

Rock Trol and Mark, Yep, the Marks website will have the info but my ratio will not be there as they are built to my order. They obviously fit nicely in between the 43 and 85. They do fill a gap marks tells me there is no market for...to me they fill a massive gap where you want slow, but not crazy slow and the 43 is still too quick

MudRunner, this is a one off for sale thread for one set, how many sets I do have is irrelevant hahaha but nah, seriously, I have bugger all of this pallet left and I wont do another run for atleast 18 months. I have a house to build. I sell them on facebook and just jumped on here to try move a couple more to get them all gone I have done 150 sets in the three or so years since the first group buy thread.

With the case grinding, the Marks instructions are the same for the 43s the 63s and the 85s, but alot of people say they can fit 43s without grinding the case. I dont know as I have never installed a set myself! The 63's do need a grind, but it is very minor. Check the instructions here

Let me know if you are keen on a set or want more info mate
