63% reductions suit GQ & GU patrol [QLD]

ITEM: 63% reductions suit GQ & GU patrol (3.29:1 ratio)

CONDITION: brand new in unopened box made by Marks 4wd.

PRICE AND PRICE CONDITIONS: 1410 + post

EXTRA INFO: I have a set of these in my own vehicle and to be honest, they are the best ratio for reductions, I have only ever had positive feedback.
I had them made as a custom order by Marks 4wd as I felt the ratios they offered (43% and 85% lower than stock) were not what I was after.
The 43% reduction still leaves the 1st gear final drive ratio faster than that of a stock 1HZ landcruiser and the 85% can be too slow and leave you range changing and just hating life in general.
These gears come with full manufacturers warranty as comes from Marks and I can post to most of Australia for $25-35. I am happy to quote freight internationally.
Probably one of the best mods I have done to my truck, I would say in terms of wheeling they made more of a change than my lockers did, as it is such an overall improvement
Cost to install varies from $300 to over $1000 with the average being around $500.
It can be done at home if you are spanner handy.
Any questions feel free to post or PM or contact me on 0433 108 569
Cheers, Andy

I'm not in the market for these unfortunately, but I can't imagine you'll have them long. Would be the ducks guts I reckon. ................one day!

G’day Andy, they sound great mate. One day when coin permits too I was previously thinking about changing diff ratios in our family wagon TD4.2T running 33” tyres from 3.9s to say 4.3s for slower track work. Don’t really want to lose highway efficiency though by doing this and your gears may be the answer. As a very rough ratio guide would your gears in low range equate to something like 4.6 diffs when off-road? Cheers Mark

God I wish I had the coin for these.

Does look like the go Mr Mark mate, wishing too here we are! Have roughly priced up front and rear diff centre swaps + a Mark’s 5th gear highway upgrade to counteract and appears double if not triple. What’s your preferred pace/ratio old mate, this 63% sounds really good but unsure of the maths?

Mark, I've got these installed for the exact same reason you mentioned. Slow track work and I don't lose fuel efficiency as it's my daily. Best way I can explain the ratio is when in low 1, I was looking for a lower gear, always too fast on the downhill runs and bloody dangerous when wet. Now I need to accelerate sometime. Have only done one trip with them in (with the old 35s) and yes, well worth it. It's a good balance for my tb45+auto.

And I'm also running 3.9s

Yeah the 5th gear thingo I wouldn't mind doing too.

Reduction gears are probably the best mod I have done to the Patrol. Absolutely transformed it off road.
Best thing to do is get onto Marks Adapters web site and look at the table which lists the actual reduction you get for different model Patrols as there is a big difference between autos and manuals. Also tyre size and diff ratios will make a difference.

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 :-)

Correct Mark. It's something that Andy has done with marks. There's a lot of info on the other Patrol forum .
